    Description / Table of Contents: A New Oxouranate(VI): K2Li4[UO6]. With a Remark about Rb2Li4[UO6] and Cs2Li4[UO6]For the first time K2Li4UO6 has been prepared by an exchange reaction of α-Li6UO6 with K2O [K:U = 2.0:1, sealed au-tube; 750°C; 30 d single crystals; 680°C, 10 d powder]. The irregular shaped single crystals, which are of yellow color and sensitive to moisture crystallize in P3m1 (Z = 1) with a = 619.27(5), c = 533.76(6) pm. The structure determination (PW 1100, AgKα R = 4.80%, Rw = 4.81% for 220 unique reflexions) reveals a new type of structure. The characteristic elements are the isolated group [UO6] and the C.N. = 12 for K+. While Li(1) has a nearly regular square of 4 O2- as coordination polyhedron, Li(2) is octahedrally surrounded.The Madelung Part of Lattice Energy (MAPLE) is calculated and discussed.In addition to K2Li4[UO6] the new oxides Rb2Li4[UO6] and Cs2Li4[UO6] are prepared as pale yellow powders which are little sensitive to moisture (both: au-tube, 680°C, 10 d). According to powder datas both compounds are isotypic with K2Li4[UO6] [Rb2Li4[UO6]: a = 622.91(5), c = 535.93(6) pm; Cs2Li4[UO6]: a = 626.70(6), c = 539.92(6) pm].
    Notes: K2Li4UO6 wurde erstmals dargestellt durch Austauschreaktion von α-Li6UO6 mit K2O [K: U = 2,0:1, Au-Rohr; Einkristalle 750°C, 30 d; Pulver 680°C, 10 d]. Die unregelmäßigen, gegen Luftfeuchtigkeit empfindlichen gelben Einkristalle kristallisieren in P3)m1 (Z = 1) mit a = 619,27(5), c = 533,76(6) pm. Nach der Strukturaufklärng (PW 1100, AgKα, R = 4,80%, Rw = 4,81% für 220 I0(hkl) liegt ein neuer Strukturtyp vor, für den neben der isolierten Gruppe [UO6] die C.N. = 12 für K+ charakteristisch ist. Vier O2- koordinieren Li(1) planar, sechs O2- Li(2) oktaedrisch.Der Madelunganteil der Gitterenergie, MAPLE wird berechnet und diskutiert.Analog konnten erstmals Rb2Li4UO6 und Cs2Li4UO6 als blaßgelbe, wenig feuchtigkeitsempfindliche Pulver dargestellt werden (jeweils Au-Rohr, 680°C, 10 d). Nach Pulverdaten sind beide mit K2Li4UO6 isotyp [Rb2Li4UO6: a = 622,91(5), c = 535,93(6) pm; Cs2Li4UO6: a = 626,70(6), c = 539,92(6) pm].

    Description / Table of Contents: Binucleating Bis-N-acylthioureas - Ligands in Trimetallamacrocycles and Polynuclear Metal ChelatesBy symmetric linking of two bidentate N-acylthioureas two types of quadridentate bis-N-acylthioureas are available which act - after di-deprotonation - as bis-bidentate S, O ligands towards polyvalent metal ions. They can form oligomeric or polymeric, cyclic or chain chelates. With 1,1,1′,1′-tetraalkyl-3,3′-terephthaloyl-bis-thioureas (H2L) we obtained oligomeric triangulotrimetalla macrocycles Ni3L3 and Cu3L3. They contain perimetric 27-membered rings, counting the internal oxygens, or 39-membered rings with the external sulfur atoms on the other hand, i. e. equal chalcogen atoms are in cis-positions within each chelate unit around the three metal ions. The trimetallamacrocyclic structure was proved by x-ray crystal and molecular structure analysis of Ni3L3 (alkyl = Et) or EPR of the corresponding Cu3L3. Diamin-linked bis-N-acylthioureas form insoluble 1:1 polymeric chelates.
    Notes: Durch geeignete symmetrische Verknüpfung zweier bidentater N-Acylthioharnstoffunktionen sind zwei Typen quadridentater Bis-N-acylthioharnstoffe zugänglich, die gegenüber mehrwertigen Metallionen als bis-bidentate S, O-Liganden fungieren. Sie können oligomere oder polymere, zyklische oder offenkettige Chelate bilden. Mit 1,1,1′,1′-Tetraalkyl-3,3′-terephthaloyl-bis-thioharnstoffen (H2L) erhielten wir oligomere triangulare Trimetallamacrocyclen Ni3L3 und Cu3L3, die perimetrische 27-Ringe mit den internen Sauerstoffligatoren bzw. 39-Ringe mit den externen Schwefelligatoren aufweisen. In jeder Chelateinheit sind die Schwefel- bzw. Sauerstoffatome in cis-Anordnung. Die makrozyklische Struktur wurde mittels RKSA (Ni3L3; Alkyl = Et) bzw. EPR (Cu3L3; Alkyl = Et) bewiesen. Diaminverknüpfte Bis-N-acylthioharnstoffe bilden unlösliche 1:1 Polymerchelate.

    Description / Table of Contents: New Rubidium Lithium Zincates: RbLiZnO2 and RbLiZn2O3For the first time colourless single crystals of RbLiZnO2 (A) and RbLiZn2O3 (B) have been prepared. Both crystallize tetragonally, A: space group I4/mmm, Z = 2, a = 351.84(4), c = 1153.3(2) pm; B: space group P42/mnm, Z = 4, a = 1 033.8(1), c = 342.8(1) pm. The crystal structures have been determined from four circle diffractometer data (MoKα; A: 155 hkl, R = 7.9%, Rw = 7.6%; B: 384 hkl, R = 7.0%, Rw = 4.6%). RbLiZnO2 has the BaZn2P2 type of structure while RbLiZn2O3 exhibits a new structure type with linear chains of face shared cubes ∞1[O4/2RbO4/2RbO4/2] as characteristic feature. For both oxides the Madelung part of lattice energy (MAPLE), and effective coordination numbers (ECoN) are calculated.
    Notes: Neu dargestellt wurden die Oxide RbLiZnO2 (A) und RbLiZn2O3 (B) in Form farbloser Einkristalle durch Tempern entsprechender Gemenge der binären Oxide. Beide Zincate kristallisieren tetragonal, A: Raumgr. I4/mmm, Z = 2, a = 351,84(4), c = 1153,3(2) pm; B: Raumgr. P42/mnm, Z = 4, a = 1 033,8(1), c = 342,8(1) pm. Die Kristallstrukturen wurden aus Vierkreisdiffraktometerdaten (MoKα) bestimmt (A: 155 hkl, R = 7,9%, Rw = 7,6%; B: 384 hkl, R = 7,0%, Rw = 4,6%). RbLiZnO2 kristallisiert im BaZn2P2-Strukturtyp, RbLiZn2O3 zeigt eine neue Struktur mit charakteristischen Würfel-Doppelketten ∞1[O4/2RbO4/2RbO4/2]. Der Madelunganteil der Gitterenergie (MAPLE) sowie effektive Koordinationszahlen (ECoN) wurden jeweils berechnet.

    Notes: Reaction of the simple alane adduct [Me3Al · HN(CH2Ph)2] (2) with the lithium amide [(PhCH2)2NLi] leads to the formation of the mixed adduct [Me3Al · (PhCH2)2NLi · HN(CH2Ph)2] (1). The crystal structures of 1 and 2 are reported. Exhibiting a four-membered, mixed-metal, mixedanion ring-core, the structure of 1 is unusual in containing a monomeric lithium dibenzylamide fragment. Such fragments generally convert to aza-allyl derivatives, so its existence here can be attributed to the stabilising effect of the attached Me3Al ligand. Crystalline 2 adopts the classical, distorted-tetrahedral arrangement of simple monomeric alane adducts. Ab initio MO calculations on model systems show that mixed adduct formation from Me3Al and Me2NLi is exothermic, while further reaction to give Me2AlNMe2 and MeLi (i.e., complete transmetallation) is endothermic.

    Description / Table of Contents: Synthesis, Characterization, and EPR Studies of Heteropoly Compounds with Iron(III) in Tetrahedral and Octahedral CoordinationThe heteropoly compounds H5[FeO4W12O36] · 6 H2O (a0 = 1216 pm), H3[Fe(OH)6Mo6O18] · 4 H2O, Na5[FeO4W12O36] · nH2O and FeH2[FeO4W12O36] · 17 H2O, for the first time obtained in this work by freeze-drying and characterized by means of chemical analysis, i.r. and u.v. spectroscopy, X-ray powder-photographs, and magnetic measurements, appear as suitable model systems for EPR investigations. They contain, like a number of known FeIII-heteropoly compounds, FeIII in FeO4 or/and FeO6 units, which are isolated from each other by structural reasons.In the Keggin-compounds M5[EIIIO4W12O36] · nH2O (I) (M = Na, Rb, TMA, TEA; E = Fe, Al, B) FeIII occupies slightly distorted tetrahedral positions (g′ ≍ 2), which are characterized by zfs-values of ≍ 10 mT and line widthes ΔB of 2.0⃛15 mT. Unlike as for I cations with different physico-chemical characteristics have only little effect on the FeIII-zfs. This holds for the Anderson-complexes M3[Fe(OH)6Mo6O18]·nH2O, (M = H, K, NH4, TMA; g′ ≍ 4.3 ΔB ≍ 67 mT) and for M5[SiO4W11O35FeO5(OH2)]·nH2O, (M = K, TMA; g′ = 4.3 ΔB = 26.5 mT). The FeO6 octahedra are more distorted than the FeO4 tetrahedra in I and therefore less susceptible for structural changes.
    Notes: Die mittels Gefriertrocknung erstmalig synthetisierten und strukturanalytisch charakterisierten Verbindungen H5[FeO4W12O36] · 6 H2O (a0 = 1216 pm), H3[Fe(OH)6Mo6O18] · 4 H2O, Na5[FeO4W12O36] · nH2O und FeH2[FeO4W12O36] · 17 H2O sind zusammen mit einer Reihe bekannter FeIII-haltiger Heteropolyverbindungen geeignete Modellsysteme für die EPR, da sie FeIII in räumlich voneinander weitgehend getrennten FeO4- oder/und FeO6-Struktureinheiten enthalten. In den Keggin-Verbindungen M5[EIIIO4W12O36] · nH2O (I) (M = Na, Rb, TMA, TEA; E = Fe, Al, B) besetzt FeIII gering verzerrte Tetraederplätze (g′ ≍ 2), die durch zfs-Beiträge von etwa 10 mT und Linienbreiten ΔB von 2,0 bis ≍ 15 mT charakterisiert sind. Sowohl in den Verbindungen vom Anderson-Typ M3[Fe(OH)6Mo6O18] · nH2O (M = H, K, NH4, TMA; g′ ≍ 4,3; ΔB ≍ 67 mT) als auch in M5[SiO4W11O35FeO5(OH2)] · nH2O (M = K, TMA; g′ = 4,3; ΔB = 26,5 mT) wirken sich Kationen mit unterschiedlichen physikalisch-chemischen Eigenschaften - anders als bei I - nur in geringem Maße auf die FeIII-zfs aus. Die FeO6-Oktaeder sind stärker verzerrt als die FeO4-Tetraeder in I und damit weniger strukturempfindlich.

    Description / Table of Contents: Crystal Structure of Li3BiO3For the first time Li3BiO3 was prepared, which crystallizes triclinic in P1with a = 902.38(35) pm, b = 973.02(48) pm, c = 923.53(46) pm, α = 114.069(38)°, β = 89.291(36)°, γ = 107.504(35)°, Z = 8. Parameters were refined by least squares (3565 out of 3969 IO(hkl)), R = 7.86%, RW = 6.93%, MOKα, 4-circle diffractometer, parameters see text.The structure shows an unknown electrostic unfavourable grouping of Bi8O2424- ·8 isolated [BiO3]3--groups are forming a cube with little distortion. The lone electronpairs are pointing inside the heating, the 3 O2- outside, respectively. Powder and single crystals, both colourless, were obtained by heating a mixture of Li2O3 (Li:Bi = 3.1:1, Ag-Bombs, 750°C, 20 d).The Madelung Part of Lattice Energy, MAPLE, and Effective Coordination Numbers, ECoN, the latter by means of Mean Fictive Ionic Radii, MEFIR, are calculated and discussed.

Die Parameter wurden nach “least squares” (3565 von 3969 I° (hkl)) verfeinert, R = 7, 86%, Rw = 6,93%, Mokα, Vierkreisdiffraktometer, Parameter siehe Text.Man erhielt Pulver bzw. Einkristalle, beide farblos, durch Tempern inniger Gemenge aus Li2O und Bi2O3 (Li:Bi = 3,1:1, Ag-Bömbchen, 750°C, 20 d). Die Struktur zeigt die neue, “Cluster”-artige, elektrostatisch ungünstige Gruppierung Bi8O2424-: Von jeweils 8 isolierten [Bio3]3--Einheiten bilden deren Bi3+ einen nur leicht verzerrten Würfel. “Freie Elektronenpaare” deuten dabei in das Innere dieses Würfels, die jeweils 3 O2- weisen entsprechend nach außen. Der Madelunganteil der Gitterenergie, MAPLE [2], sowie Effektive Koordinationszahlen, ECoN [2], diese über Mean Fictive Ionic Radii MEFIR werden berechnet und diskutiert.

    Description / Table of Contents: Thermolysis of Potassium and Ammonium Pentafluorometallate Hydrates. An in situ-EPR StudyIn situ-EPR investigations on Fe3+ ions in K2AlF5 · H2O, (NH4)2[AlF5(H2O)], and (NH4)2[FeF5(H3O)] were carried out in the temperature range from 25°C to 230°C. The Fe3+ ions occupy in these compounds Al3+ sites with rhombic and axial symmetry. These Fe3+ ions are suszeptible for structural changes at the thermolysis. Simultaniously Fe—O—Fe species are formed, yielding autonomous phases in this process. The conclusions, done from EPR investigations agree with results of other methods (e.g. X-ray and thermal analysis) and complete them in unique manner.
    Notes: In situ-EPR-Untersuchungen von Fe3+-Ionen in K2AlF5 · H2O, (NH4)2[AlF5(H2O)] und (NH4)2[FeF5(H2O)] wurden im Temperaturbereich zwischen 25°C und 230°C durchgeführt. Dabei zeigte sich, daß Fe3+-Ionen in diesen Verbindungen Al3+-Gitterplätze rhombischer und axialer Symmetrie besetzen. Diese Fe3+-Ionen zeigen in empfindlicher Weise Strukturänderungen bei der Thermolyse an. Gleichzeitig entstehen bei diesem Prozeß Fe—O—Fe-Spezies in selbständigen Phasen. Die Ergebnisse zeigen, daß EPR-Untersuchungen zusätzliche Strukturaussagen liefern und so röntgenographische und andere Aussagen in spezifischer Weise ergänzen.
