Diphenyl-2-pyridylphosphine as a bidentate ligand in the coordination of dicobalt octacarbonyl; X-ray crystal structures of Co2(CO)4(μ-P,N-PPh2py){μ-HCCSiMe 3}, and Co4(CO)10(μ-P,N-PPh2py)

Under mild conditions, the reaction of Co2(CO)8 with HCCSiMe3 in the presence of PPh2py gave a binuclear cobalt carbonyl complex, Co2(CO)4(η2-μ2-HCCSiMe 3)(μ-PPh2py) (1a), which has both zero-valent cobalt centers coordinated by a bidentate ligand, PPh2py. PPh2py is also an effective ligand in promoting the yield of 2,5-bis(trimethylsilanyl)cyclopenta-2,4-dien-1-one. A cobalt cluster complex, Co4(CO)10(μ-P,N-PPh2py) (9) was obtained when two equivalents of Co2(CO)8 were reacted with PPh2py at a higher temperature. The phosphorus and nitrogen atoms of the ligand coordinate to cobalt in the basal and apical positions, respectively. These two compounds, 1a and 9 were characterized by spectroscopic means as well as X-ray crystal structure determination.
