Binuclear oxomolybdenum(V) chlorides: Molecular structure of Mo2O4Cl2(DMF)4 and Mo2O4Cl2(bipy)2 · DMF

Reduction of MoO2Cl2(DMF)2 (DMF = dimethylformamide) with PPh3 in mild conditions afforded the dinuclear species Mo2O3Cl4(DMF)4. Related compounds could be prepared by substitution of DMF with stronger bases. The molecular structures of Mo2O4Cl2(DMF)4, and Mo2O4Cl2(bipy)2 (bipy = 2,2′-bipyridine) have been established by X-ray diffraction analysis.
