Abstract
Abstract The electrochemical behavior of the di-μ-oxo, μ-oxo-μ-sulfido and di-μ-sulfido dinuclear molybdenum(V) complexes ligating a series of dithiocarbamates, [Mo2O4−nSn(R2dtc)2] (n = 0—2; R2dtc− = dithiocarbamate), was investigated in dichloromethane. Each complex undergoes a one-electron quasi-reversible reduction, followed by a homogeneous chemical reaction, except for the di-μ-sulfido complex [Mo2O2S2(Ph2dtc)2] which shows a complicated electrochemical process. The chemical stability of the one-electron reduction products of [Mo2O4−nSn(R2dtc)2] increases with increase in the number of bridging sulfides and in the electron-donating ability of the substituents on the dithiocarbamate ligands.
