Monomere flüchtige Alkoxide von Chrom und Bismut

Monomeric Volatile Alkoxides of Chromium and Bismuth The β1-methoxy alcohol HOCMe2CH2OMe (1) yields monomeric (mononuclear), highly volatile and soluble complexes M(OCMe2CH2OMe)33a, b of chromium(III) and bismuth(III), respectively, upon treatment with the amide precursors Cr[N(iPr)2]3 (2a) and Bi[N(SiMe3)2]3 (2b). A single-crystal X-ray diffraction analysis of 3a was performed because of the novelty of this particular compound being the first thermostable monomeric alkoxide of trivalent chromium. 3a exhibits an octahedral structure with six oxygen atoms surrounding the metal atom. Three chelating O,O′ ligands coordinate to Cr(III) in a mer configuration.
