摘要：

The crystal structures of the complexes of 3,3-dimethyl-2,2'-bipyridine (L), cis-[W(CO)4L], cis-[Mo(CO)4L].C4H6 and cis-[Cr(CO)4L].C6H6 have been determined by X-ray diffraction. These structures show that repulsion between the methyl groups is principally responsible for the geometric distortion in each complex. Within the ligand, L, the two pyridine rings suffer distortion, in opposite directions, to pseudo-boat conformations so as to optimize metal-nitrogen binding. The benzene solvent molecules are arranged in a layer structure alternating with units of the metal complex. The metal complex molecule is beyond van der Waals contact with the benzene solvent molecule in each case.
