The crystal structure of benzyltricarbonyl-η5-cyclopentadienylmolybdenum(II) and related substituted benzyl complexes
The crystal structures of [(η-CH)(CO)Mo(CHCH)], [(η-CH(CO)Mo(CHCH-2-Me)] and [(η-CH)(CO)Mo(CHCH-2,4,6-Me] have been determined. With increases in intramolecular interaction arising from the degree of ortho-substitution in the benzyl group, the molybdenummethylene carbon bond length (MoC(11)) and the bond angle, (MoC(11)C(1)), around the methylene carbon generally increase. The structural features are compared with rates of CO insertion into the molybdenumcarbon bonds in these molecules
