    摘要: Under mild conditions, the reaction of Co-2(CO)(s) with HC=CSiMe3 in the presence of PPh(2)py gave a binuclear cobalt carbonyl complex, Co-2(CO)(4)(eta(2)-mu(2)-HC=CSiMe3)(mu-PPh(2)py) (1a), which has both zero-valent cobalt centers coordinated by a bidentate ligand, PPh(2)py. PPh(2)py is also an effective ligand in promoting the yield of 2,5-bis(trimethylsilanyl)cyclopenta-2,4-dien-1-one. A cobalt cluster complex, Co-4(CO)(10)(mu-P,N-PPh(2)py) (9) was obtained when two equivalents of Co-2(CO)(8) were reacted with PPh(2)py 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, la and 9 were characterized by spectroscopic means as well as X-ray crystal structure determination.
