Abstract
Mono(maleonitriledithiolene)sulfidomolybdenum(IV) complex, [MoS(S4)(mnt)]2− (2; mnt=maleonitriledithiolene) was synthesized by the substitution reaction of a tetrasulfido ligand of the known [MoS(S4)2]2− (1) upon reaction with one or even excess equivalent of Na2(mnt) in aqueous MeCN solution in air. Surprisingly, 2 undergoes dimerization on treatment with alkyl halide such as MeI and PhCH2Br to form bis(μ-sulfido)dimolybdenum(V) species, [{MoS(mnt)}2(μ-S)2]2− (3). These complexes have been characterized by IR, UV/VIS spectroscopy, cyclic voltammetry, elemental analysis, and by X-ray crystal-structure analysis. Differences in the relative stability and electrochemical behavior of 1, 2, and 3 have been correlated with theoretical calculations at DFT level.
