    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.

Die Verbindung kristallisiert monoklin, Raumgruppe C2/c mit a = 23,143(5), b = 8,342(2), c = 26,382(5) Å, β = 95,12(3), Z = 4. Die Bindungslänge Tc≡N beträgt 1,615(6) Å. Tc und N(l) befinden sich auf einer zweizähligen kristallographischen Achse. Der Komplex hat quadratisch-pyramidale Geometrie. Die vier Schwefelatome bilden die Grundfläche der Pyramide, deren Spitze vom Nitrido-Stickstoff eingenommen wird. Das Technetiumatom befindet sich um 0,62 Å über der Grundfläche.
    Notes: (Bu4N)2[TcN(dmit)2] (dmit2- = isotrithionedithiolate) was prepared from Na2dmit, (Bu4N)[TcNCl4] and (Bu4N)Cl in acetonitrile. The compound crystallises in the monoclinic space group C2/c with a unit cell of the dimensions a = 23.143(5), b = 8.342(2), c = 26.382(5) Å, β = 95.12(3), Z = 4. The Tc≡N bond distance is comparatively short at 1.615(6) Å. Tc and N(1) are situated on a two-fold crystallographic axis. The general coordination geometry is a square pyramid with the four sulfur atoms forming the basal plane and the nitrido nitrogen at the apex. The technetium is located 0.62 Å above the plane defined by the four sulphurs.

    Description / Table of Contents: Molecular Structures of Copper(II) and Iron(III) Chloro Complexes with di- and monoprotonated N-(pyrid-2-ylmethyl)ethylenediamine-N,N′,N′-triacetate (H2pedta-; Hpedta2-)The molecular structures of two complexes of di- and monoprotonated N-(pyrid-2-ylmethyl)ethylenediamine-N,N′,N′ -triacetate (pedta3-) with CuII and FeIII as central atoms have been determined by single crystal X-ray diffraction methods. Both complexes have a distorted octahedral coordination with H2pedta- and Hpedta2- as pentadentate ligands and a chloride ion occupying the sixth coordination site. The different oxidation states of the central atoms result in a completely different coordination behaviour of the carboxyl groups. In both complexes one of the —CH2—COOH groups is uncoordinated. In the FeIII complex, the central atom is coordinated by the hydroxylic O atoms of the deprotonated carboxyl groups. Contrary to this in the CuII complex, the central atom is coordinated by the carbonylic O atoms. One of the coordinated carboxyl groups is protonated and the other is deprotonated. All protonated carboxyl groups in both complexes form intermolecular hydrogen bonds.
    Notes: Die Molekülstrukturen zweier Komplexe von di- bzw. monoprotoniertem N-(Pyrid-2-ylmethyl)ethylendiamin-N,N′,N′-triacetat (pedta3-) mit CuII bzw. FeIII als Zentralatome wurden durch Röntgenkristallstrukturanalyse bestimmt. Beide Komplexe haben eine verzerrt oktaedrische Koordination, in der H2pedta- bzw. Hpedta2- als fünfzähnige Liganden wirken. Die sechste Koordinationsstelle wird durch ein Chlorid-Ion besetzt. Die unterschiedliche Oxidationsstufe der Zentralatome führt zu einem unterschiedlichen Koordinationsverhalten der Carboxylgruppen. In beiden Komplexen ist eine der —CH2—COOH-Gruppen unkoordiniert. Im FeIII-Komplex erfolgt die Koordination über die hydroxylischen O-Atome der deprotonierten Carboxylgruppen. Im Gegensatz dazu beobachtet man im CuII-Komplex Koordination über die carbonylischen O-Atome, wobei eine der beiden Carboxylgruppen protoniert und die andere deprotoniert vorliegt. Von allen protonierten Carboxylgruppen in beiden Komplexen gehen intermolekulare Wasserstoffbrückenbindungen aus.

    Description / Table of Contents: Syntheses of Metal Carbonyls. 23. Crystal Structure and Reactivity of Heptamethylindenyl Carbonyl Metal ComplexesReaction of heptamethylindene (C9(CH3)7, 1) with Re2(CO)10 yields [η5-C9(CH3)7]Re(CO)3 (2), which reacts with NO+BF4- to form the cationic complex [{η5-C9(CH3)7}Re(CO)2NO]+BF4- (3). Irradiation of 2 with UV light in the presence of triethyl phosphite leads to formation of [η5-C9(CH3)7]Re(CO)2[P(OC2H5)3] (4). Alkylation of (CH3)3SnCl with Ind*Li gives [η1-C9(CH3)7]Sn(CH3)3 (5). All compounds were characterized by spectroscopic methods. The molecular structures of 3 and 5 were determined by single crystal X-ray diffraction (3: P21/n (14), a = 1497.7(4) pm, b = 879.0(2) pm, c = 1609.0(4) pm and β = 110.99(2)°, R1 = 0.038, wR2 = 0.080; 5: P21/n (14), a = 726.1(1) pm, b = 2930.7(3) pm, c = 930.0(1) pm and β = 112.834(5)°, R1 = 0.044, Rw = 0.048). Complexes 2-4 exhibit a piano stool configuration with a η5-coordinated permethylindenyl ligand (Ind*). Compound 5 displays a η1 -coordination of the Ind* ligand. Temperature enhancement causes a hapticity change, as observed by NMR spectroscopy.
    Notes: Heptamethylinden (C9(CH3)7H, 1) reagiert mit Re2(CO)10 zu [η5-C9(CH3)7]Re(CO)3 (2), das durch Umsetzung mit NO+BF4- die kationische Verbindung[{η5-C9(CH3)7}Re (CO)2NO]+BF4- (3) und unter Bestrahlung mit UV-Licht in Anwesenheit von Triethylphosphit [η5-C9(CH3)7]Re(CO)2[P(OC2H5)3] (4) ergibt. Durch Alkylierung von (CH3)3SnCl wird [η1-C9(CH3)7]Sn(CH3)3 (5) erhalten. Alle Verbindungen wurden mit spektroskopischen Methoden vollständig charakterisiert. Von 3 und 5 wurden die Kristallstrukturen röntgenstrukturanalytisch bestimmt (3: P21/n (14), a = 1497.7(4) pm, b = 879.0(2) pm, c = 1609.0(4) pm und β = 110.99(2)°, R1 = 0.038, wR2 = 0.080; 5: P21/n (14), a = 726.1(1) pm, b = 2930.7(3) pm, c = 930.0(1) pm und β = 112.834(5)°, R1 = 0.044, Rw = 0.048). Während bei den Komplexen 2-4 der Heptamethylindenligand (Ind*) einen Halbsandwich-Komplex bildet (η5-Bindung zum Metall), so liegt in Derivat 5 erwartungsgemäß eine σ-Bindung zwischen einem C-Atom des Ind*-Liganden und dem Metallzentrum vor. Bei Temperaturerhöhung tritt eine Änderung der Haptizitätsverhältnisse ein (NMR-Evidenz).
