摘要：

Oxidation of [(MeC5H4)Mo(CO)3]2 (1) by nitrobenzene in refluxing toluene affords three dimolybdenum oxo-imido complexes [(MeC5H4)2Mo2O2(mu-O)(mu-NPh)] (2), [(MeC5H4)MoO(mu-NPh)]2 (3), and [(MeC5H4)2Mo2O(NPh)(mu-O)(mu-NPh)] (4). Complexes 3 and 4 are isomers but do not interconvert. Complex 4 undergoes facile hydrolysis in hydrocarbon solvents giving 2 and aniline. The X-ray crystal structures of compounds 2 and 3 have been determined. Both structures display a trans-disposition of methylcyclopentadienyl ligands and terminal oxo ligands. The Mo2(mu-X)2 metallacore geometries are rigorously planar with the phenyl substituent(s) of the imido ligands being tilted slightly out of this plane. The Mo-Mo distances correspond to normal single bonds.
