Chemistry of oxomolybdenum(V) and (VI) complexes incorporating oxygen, nitrogen, and/or sulfur donor atoms. II. Synthesis and characterization of some heteroleptic dioxomolybdenum(VI) complexes of the type [MoO2Cl(L)L '] (L = dithiocarbamates or xant

摘要

Heteroleptic dioxomolybdenum(VI) complexes of the type [MoO2Cl(L)L'] (L=diethyl dithiocarbamate, diisopropyl dithiocarbamate, pyrrolidine dithiocarbamate, piperidine dithio-carbamate, methyl xanthate or isopropyl xanthate; L'=triphenylphosphine oxide OPPh3 or dimethyl sulfoxide DMSO) have been synthesised by treating equimolar amounts of MoO2Cl2(L')(2) with the sodium or potassium salts of the corresponding dithiocarbamates or xanthates. All of these derivatives are coloured solids which are soluble in polar solvents. They have been characterized by elemental analyses and spectral (electronic, IR, NMR) studies. [References: 14]
