    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.
    Notes: Die Titelverbindung entsteht in Form farbloser Kristalle bei der Reaktion von Sb5O7Cl11 mit Dichlormethan bei 20°C. 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: Ligand Exchange Reactions of Bis(acetylacetonato)dioxo-molybdenum(VI). Crystal Structures of [Salicylaldehyde-benzoylhydrazonato(2-)]dioxo-methanol-molybdenum(VI) and [Benzoylacetone-benzoylhydrazonato(2-)]dioxo-triphenylphosphaneoxide-molybdenum(VI)The products of ligand exchange reactions between bis(acetylacetonato)dioxo-molybdenum(VI) and tridentate diacidic ligands H2L in the presence of triphenylphosphane were found by mass spectrometry to be complexes of the type MoO2L. In the case of salicylaldehyde 2-hydroxyanil MoL2 could also be identified. The compounds MoO2L were crystallized as complexes with methanol or triphenylphosphane oxide.Crystallographic data see “Inhaltsübersicht”.

Beim Salicylaldehyd-2-hydroxyanil konnte auch MoL2 nachgewiesen werden.
