metal-organic compounds
The title structure, [Mo2(CH3O)2]0.75.[Mo2Cl2(CH3O)6(O)2]0.25, contains two crystallographically independent centrosymmetric molecules, each of which has a major disorder component of [MoO(OMe)4]2 and a minor component of [MoOCl(OMe)3]2 with a cis arrangement of chloro and oxo ligands. The oxo ligands lie in the `equatorial' plane of the metal atoms and bridging ligands. The methoxo bridges are markedly asymmetric as a consequence of the strong trans influence of the terminal oxo ligands compared with terminal methoxy ligands. Coordination of the Mo atom is distorted octahedral.
