Synthesis and characterization of binuclear oxomolybdenum(V) and dioxomolybdenum(VI) O,O′-ditolyl dithiophosphate complexes.

Binuclear oxomolybdenum(V) and Dioxomolybdenum(VI) O,O′-ditolyl dithiophosphate complexes were synthesized. These synthesized complexes were characterized by elements analysis and IR, 1H and 31P NMR spectroscopy and, in three cases, by X-ray crystallography. Mo2O3[S2P(OC6H4Me-o)2]4 and Mo2O3[S2P(OC6H4Me-m)2]4, the environment around each molybdenum atom can be described as the expected distorted octahedral. The geometry around the Mo atom in MoO2[S2P(OC6H4Me-p)2]2 is again distorted octahedral.
