Volatile Dimethylgold(III) β-Iminovinylthionates: Synthesis, Structure, and Properties

摘要

Volatile dimethylgold(III) β-iminovinylthionates, (CH3)2Au(CH3CSCHC(NH)CH3) (I) and (CH3)2Au(CF3CSCHC(NH)CH3) (II), were studied. For complexes I and n, the synthesis is described and data from elemental analysis, IR and UV/Vis spectra, DTA, and X-ray diffraction are given. The structures of I and II are composed of monomeric complexes combined into polymeric stack-type associates. The distorted square environment of gold is formed by sulfur and nitrogen atoms of the chelating ligand and two carbon atoms of the methyl groups. For complex I, the average Au-S bond length is 2.260 A, the Au-N bond length is 2.137 A, and the chelate angle SAuN is 94.1°; for II, these values are 2.355 A, 2.088 A, and 93.7°, respectively.
