Dinuclear oxomolybdenum(VI) acetylacetonates: Crystal and molecular structure of Mo2O5(acac)2L2 (L = D2O, DMF)

The behavior of MoO2(acac)2 (acac = acetylacetonate) towards representative amines, amides, sulfoxides and phosphine oxides in common solvents has been examined. Compounds of the composition Mo2O5(acac)2L2 [L = H2O, D2O, dimethylformamide (DMF), dimethylacetamide (DMA), dimethylbenzamide (DMBA), tetramethylurea (TMU), dimethylsulfoxide (DMSO), dibutylsulfoxide (Bu2SO), p-tolylsulfoxide (p-Tol2SO), tributylphosphine oxide (OPBu3), triphenylphosphine oxide (OPPh3), hexamethylphosphoramide (HMPA)], derived from partial hydrolysis of MoO2(acac)2 followed by condensation and coordination of L, can readily be isolated. The crystal and molecular structures of Mo2O5(acac)2L2 (L = D2O, DMF) have been established by X-ray diffraction analysis.
