Synthesis and characterization of Bis(μ-sulfido)bis[{O,O-dimethyldithiophosphato}oxomolybdenum(V)]. Crystal structure of Mo₂O₂(Φ-S₂)[S₂P(OMe)₂]₂.C₆H₆

Bis(mu-sulfido)bis[{O,O-dimethyldithiophosphato}oxomolybdenum(V) was prepared by dropwise addition of an ethanolic solution of the ammonium salt of O,O-dimethyldithio-phosphoric acid to a hot aqueous solution of MoCl5. The X-ray structure of Mo2O2(Phi-S-2)[S2P(OMe)(2)](2).C6H6 was determined. Crystal data: Monoclinic, P2(1)/n, a = 6.9788(6), b = 22.616(3), c = 14.633(1) angstrom, beta = 101.193(9)degrees, V = 2265.5(4) angstrom(3), Z = 4. The immediate environment around the two molybdenum atoms is essentially square pyramidal if the Mo-Mo interaction is ignored. The terminal oxygen atoms are in the syn conformation.
