Synthesis and Structures of the Ligands 1-Methylimidazol-2-yl(pyridin-2-yl)-methanone {(py)(mim)CO} and 1-Benzylimidazol-2-yl(1-phenylaldimine)(PhN=CHbim) as their Tetracarbonylmolybdenum(0) Complexes[Mo(CO)4(L2-N,N')]

The complexes [Mo(CO)4(L2-N,N')] [L2 = 1-methylimidazol- 2-yl(pyridin-2-yl)methanone and 1-benzylimidazol-2-yl(1- phenylaldimine)] have been synthesized from hexacarbonylmolybdenum(0) in order to define the coordination characteristics of the bidentate nitrogen-donor ligands; the complexes exhibit distorted octahedral coordination for molybdenum(0) and cis-bidentate ligand configurations
