Mixed-ligand cluster [Mo3S4(Dtp)2(μ-AcO)Cl(Me2Bipy)]: Synthesis and structure

Mixed-ligand cluster [Mo3S4(Dtp)(2)(mu-AcO)Cl(Me(2)Bipy)] center dot CHCl3 (I center dot CHCl3), where Dtp is (EtO)(2)PS2, was synthesized by the reaction of the molybdenum aqua complex [Mo3S4(H2O)(9)](4+) with 4,4'-dimethyl-2,2'-bipyridine (Me(2)Bipy) and phosphorus sulfide (P4S10) in ethanol followed by chromatographic separation on silica gel and crystallization in the presence of acetic acid. The crystal structure of I center dot CHCl3 was determined by X-ray diffraction analysis. The synthesized compound was characterized by the IR and NMR spectra and elemental analysis. The electronic structure of the synthesized compound was established, and its electrochemical behavior in a solution was studied.
