    Description / Table of Contents: Synthesis, IR Spectrum, and Crystal Structure of Sb12O18(OH)2Cl22 · 2CH2Cl2The title compound has been prepared by the reaction of Sb5O7Cl11 with dichloromethane at 20°C, forming colourless, moisture sensitive crystals. Sb12O18(OH)2Cl22 · 2CH2Cl2 crystallizes monoclinically in the space group P21/n with two formula units per unit cell. Structure solution with 2696 unique observed reflections, R = 0.042. Lattice dimensions at 19°C: a = 1350.2, b = 1466.7, c = 1392.9 pm, b̃ = 97.925°. The distorted octahedrally coordinated antimony atoms, bridged by oxygen atoms, exhibit a molecular array which may be seen as a fragment of the rutile type structure, isolated by terminal chloride ligands. The solvate molecule is associated by a hydrogen bridge OH···Cl.

Sb12O18(OH)2Cl22 · 2CH2Cl2 kristallisiert monoklin in der Raumgruppe P21/n mit zwei Formeleinheiten pro Elementarzelle. Strukturlösung mit 2696 unabhängigen beobachteten Reflexen, R = 0,042. Gitterkonstanten bei 19°C: a = 1350,2; b = 1466,7; c = 1392,9 pm, b̃ = 97,925°. Die verzerrt oktaedrisch koordinierten und über Sauerstoffatome verbrückten Antimonatome bilden ein molekulares Gerüst, das als ein durch terminale Chlorliganden isolierter Ausschnitt aus der Rutilstruktur angesehen werden kann. Das Solvatmolekül ist durch eine Wasserstoffbrücke OH…Cl assoziiert.

    Description / Table of Contents: The Crystal Structures of the Vanadium Weberites Na2MIIVIIIF7 (MII = Mn, Ni, Cu) and of NaVF4At single crystals of the vanadium(III) compounds NaVF4 (a = 790.1, b = 531.7, c = 754.0 pm, β = 101.7°; P21/c, Z = 4), Na2NiVF7 (a = 726.0, b = 1031.9, c = 744.6 pm; Imma, Z = 4) and Na2CuVF7 (a = 717.6, b = 1043.5, c = 754.6 pm; Pmnb, Z = 4) X-ray structure determinations were performed, at Na2MnVF7 (a = 746.7, c = 1821.6 pm; P3221, Z = 6) a new refinement. NaVF4 crystallizes in the layer structure type of NaNbO2F2. The fluorides Na2MIIVF7 represent new orthorhombic (MII = Ni; Cu) resp. trigonal (MII = Mn) weberites. The average distances within the [VF6] octahedra of the four compounds are in good agreement with each other and with data of related fluorides (V—F: 193.3 pm). The differences between mean bond lengths of terminal and bridging F ligands are 5% in NaVF4, but less than 1% in the weberites. Details and data for comparison are discussed.
    Notes: An Einkristallen der Vanadium(III)-Verbindungen NaVF4 (a = 790,1, b = 531,7, c = 754,0 pm, β = 101,7°; P21/c, Z = 4), Na2NiVF7 (a = 726,0, b = 1031,9, c = 744,6 pm; Imma, Z = 4) und Na2CuVF7 (a = 717,6, b = 1043,5, c = 754,6 pm; Pmnb, Z = 4) wurden Röntgenstrukturbestimmungen durchgeführt, an Na2MnVF7 (a = 746,7, c = 1821,6 pm; P3221, Z = 6) eine neue Verfeinerung. NaVF4 kristallisiert in der Schichtstruktur des NaNbO2F2-Typs. Die Fluoride Na2MIIVF7 sind neue orthorhombische (MII = Ni; Cu) bzw. trigonale (MII = Mn) Weberit-Vertreter. Die mittleren Abstände in den [VF6]-Oktaedern der vier Verbindungen stimmen gut miteinander und mit Daten in verwandten Fluoriden überein (V—F: 193,3 pm). Die Unterschiede zwischen den mittleren Abständen terminaler und verbrückender F-Liganden betragen in NaVF4 5%, in den Weberiten aber weniger als 1%. Einzelheiten und Vergleichsdaten werden diskutiert.

    Description / Table of Contents: High Pressure Syntheses and Transformations of Hexagonal Elpasolithes A2IBIMIIIF6Hexagonal-rhombohedrally in the structure type of Cs2NaCrF6 crystallizing elpasolithes Rb2LiMF6 and Cs2NaMF6 (MIII = Al, Ga, V, Cr, Fe) were transformed to cubic modifications (K2NaAlF6 type) by high pressure application (15-100 kbar). In addition intermediate high pressure phases with the hexagonal structure of high temperature K2LiAlF6 could be obtained in some cases. The lattice constants of these compounds are reported, as well as those of hexagonal elpasolithes Tl2LiMF6 and Cs2LiMF6 which only form, if they are synthesized under pressure. The results are discussed in connection with the Goldschmidt tolerance factor t′ = √2(rA + rF)/(rB + rM + 2rF) of the elpasolithes mentioned.
    Notes: Von hexagonal-rhomboedrisch im Cs2NaCrF6-Typ kristallisierenden Elpasolithen Rb2LiMF6 und Cs2NaMF6 (MIII = Al, Ga, V, Cr, Fe) konnten durch Hochdruckanwendung (15-100 kbar) kubische Modifikationen (K2NaAlF6-Typ) erhalten werden. Als intermediäre Hochdruckphasen ließen sich in einigen Fällen außerdem Modifikationen mit der hexagonalen Struktur von Hochtemperatur-K2LiAlF6 fassen. Die Gitterkonstanten dieser Verbindungen werden mitgeteilt, ebenso wie diejenigen neuer hexagonaler Elpasolithe Tl2LiMF6 und Cs2LiMF6, die sich nur bilden, wenn die Synthese unter Druck erfolgt. Die Ergebnisse werden im Zusammenhang mit dem Goldschmidtschen Toleranzfaktor t′ = √2(rA + rF)/(rB + rM + 2rF) der genannten Elpasolithe diskutiert.

    Description / Table of Contents: Relations of Distances and Coordination in the Layer Structures of the Ternary Fluorides K2MF4 and K3M2F7 (MII = Mg, Mn, Co=Zn)Results of X-ray single crystal structure refinements of the compounds K2MF4 (M = Mg, Mn, Co, Ni) and K3M2F7 (M = Mn, Co, Ni), all crystallizing in the tetragonal space group I4/mmm of the K2NiF4 and Sr3Ti2O7 type, resp., are reported. The distances obtained are discussed, including data of the compounds with M = Cu, Zn. The influence of the KF9 coordination is made responsible for the fact, that the octahedral MF6 dimensions are much the same as in the corresponding perovskites KMF3. The shortest K—F distance of this KF9 group, occuring in both layer structure types, decreases against lattice widening from 263.4 pm (K2MgF4) to 258.0 pm (K2MnF4). The charge ratio calculated from the KF9 coordination for the unlike bonded anions leads to a better balanced charge distribution in the K2MF4 type, as is obtained by applying Pauling's rules.
    Notes: Ergebnisse röntgenographischer Einkristallstrukturverfeinerungen an den im K2NiF4- bzw. Sr3Ti2O7-Typ kristallisierenden Verbindungen K2MF4 (M = Mg, Mn, Co, Ni) und K3M2F7 (M = Mn, Co, Ni), die alle der tetragonalen Raumgruppe I4/mmm angehören, werden mitgeteilt. Die resultierenden Abstandsdaten werden unter Einbeziehung der Verbindungen mit M = Cu, Zn diskutiert. Die weitgehend den zugehörigen Perowskiten KMF3 entsprechenden Abstandsverhältnisse in den MF6-Oktaedern werden dem Einfluß der KF9-Koordination zugeschrieben, deren kürzester Abstand K—F in beiden Schichtstrukturtypen entgegen der Gitteraufweitung von 263,4 pm (K2MgF4) auf 258,0 pm (K2MnF4) abnimmt. Das aus der KF9-Koordination berechnete Ladungsverhältnis der ungleich gebundenen Anionen führt zu einer ausgeglicheneren Ladungsbilanz für den K2MF4-Typ, als die Anwendung der Paulingschen Regeln.

    Description / Table of Contents: Structures of Cesium-containing Fluorides. V. Pseudohexagonal Tungsten Bronze Structure of the Monoclinic Phase Cs0.4Zn0.4Fe1.6F6 and Related Cesium Transition Metal FluoridesThe crystal structure of the pseudohexagonale phase Cs0.4Zn0.4Fe1.6F6 was refined in the monoclinic space group P21 (a = 747.4, b = 763.6, c = 746.1 pm, β = 120.0°, z = 3). Using 1067 single crystal reflections R = 6.3% was reached. Compared to the hexagonal tungsten bronze structure the corner-sharing of octahedra shows pronounced angles also along the unique axis (M—F—M = 159.0°). The average bridge angle in the framework of tilted octahedra is 149.6°. Structural relations are discussed.
    Notes: Die Kristallstruktur der pseudohexagonalen Phase Cs0,4Zn0,4Fe1,6F6 konnte in der monoklinen Raumgruppe P21 (a = 747,4 b = 763,6, c = 746,1 pm, β = 120,0°, z = 3) unter Auswertung von 1 067 Einkristallreflexen auf R = 6,3% verfeinert werden. Im Vergleich zur Struktur der hexagonalen Wolframbronzen ist die Oktaeder-Eckenverknüpfung auch längs der ausgezeichneten Achse deutlich gewinkelt (M—F—M = 159,0°). Der mittlere Brückenwinkel im Raumnetz der verkippten Oktaeder beträgt 149,6°. Die Strukturverhältnisse werden diskutiert.

    Description / Table of Contents: Crystal Structure of a High Temperature Modification of Barium-Zinc-Iron(III) Fluoride BaZnFeF7A metastable high temperature form of BaZnFeF7 prepared at 750°C crystallizes monoclinically (a = 560.3(1), b = 997,1(3), c = 958.4(4) pm, β = 92.80(4)°, Z = 4) in the same space group P21/c as the low temperature form. The X-ray structure determination (RG = 5.2— for 2426 independent reflections) showed analogy in the coordination behaviour of Zn2+ and Fe3+ cations, which occupy in an ordered way groups of two edgesharing octahedra, at each of which one ligand remains unbridged (mean distances Zn—F = 204.7 pm, Fe—F = 194.6 pm). The linking of double octahedra via corners to form a threedimensional framework involves strongly bent fluorine bridges (average Zn—F—Fe = 126.5°). Related structures are discussed.
    Notes: Eine bei 750°C in Einkristallen dargestellte metastabile Hochtemperatur-form von BaZnFeF7 kristallisiert monoklin (a = 560,3(1), b = 997,1(3), c = 958,4(4) pm, β = 92,80(4)°, Z = 4) in derselben Raumgruppe P21/c, wie die Tieftemperaturform. Die röntgenographische Strukturbestimmung (RG = 5,2 -  für 2 426 unabhängige Reflexe) ergab koordinationschemisch analoges Verhalten für Zn2+- und Fe3+-Kationen, die geordnet kantenverknüpfte Gruppen von zwei Oktaedern besetzen, an denen je ein Ligand unverbrückt bleibt (mittlere Abstände Zn—F = 204,7 pm, Fe—F = 194,6 pm). Die Eckenverknüpfung der Doppeloktaeder zu einer Raumnetzstruktur verläuft über stark gewinkelte Fluorbrücken (Mittel Zn—F—Fe = 126,5°). Verwandte Strukturen werden diskutiert.

    Description / Table of Contents: Structures of Fluorides with Caesium. IV. The Crystal Structure of CsCrF4 - a Novel Tetra-fluorometallate Type with Chain StructureThe crystal structure of the hexagonal compound CsCrF4, crystallizing in space group P62m-D3h3, was determined: a =9.650(5), c = 3.857(3) Å, z = 3, R = 0.023 for 220 symmetrically independent reflections hkl. CsCrF4 is a new type of chain structure, containing three chains of octahedra sharing trans corners along [001] and connected by cis corners to form a triple chain. The bridging angles are Cr—F—Cr = 177.9° and 149.3°, the corresponding distances Cr—F = 1.929 and 1.940 Å, resp., compared to 1.851 Å for the terminal ligands. The results are discussed and relations to other structures shown.

CsCrF4 stellt eine neuen Typ von Kettenstruktur dar, in dem drei längs [001] über trans-Ecken verknüpfte Oktaederketten miteinander über cis-Ecken zu einem Dreierstrang verbunden sind. Die Brückenwinkel betragen Cr—F—Cr 177,9° bzw. 149,3°, die entsprechenden Abstände Cr—F = 1,929 bzw. 1,940 Ä, gegenüber 1,851 Å für die terminalen Liganden. Die Ergebnisse werden diskutiert und Beziehungen zu anderen Strukturen aufgezeigt.
