Bis[[mu]2-bis(diphenylphosphino)methane]bis([mu]2-ethane-1,2-dithiolato)-[mu]4-sulfido-[mu]2-sulfido-disulfidodimolybdenum(V)disilver(I) dimethylformamide trisolvate

Abstract: Treatment of [Et4N]2[(edt)2Mo2S2([mu]-S)2] (edt = ethanedithiolate) with two equivalents of Ag(CH3CN)4ClO4 in the presence of bis(diphenylphosphino)methane (dppm) ligand gives rise to the title tetranuclear cluster, [Ag2Mo2(C2H4S2)2S4(C25H22P2)2]·3C3H7NO. The complex molecule and one of the dimethylformamide (DMF) solvent molecules occupy special positions on a mirror plane. The molecular structure of the complex may be visualized as being built of [Mo2S2([mu]-S)2(edt)2]2- dianions and [Ag2(dppm)2]2+ dications connected by two Ag-[mu]-Sedt and two Ag-[mu]4-S bonds.
