dc.description.abstractTreatment of Co-4(CO)(12) with an excess of trimethylsilylacetylene (TMSA) in the presence of tri(2-thienyl)phosphine in THF at 25 degreesC for 2 hours yielded six compounds. Two pseudo-octahedral, alkyne-bridged tetracobalt clusters, [Co-4(mu(4)-eta(2)-HCequivalent toCSiMe(3))(CO)(10)(mu-CO)(2)] (4) and [Co-4(mu(4)-eta(2)-HCequivalent toCSiMe(3))-(CO)(9)( (mu-CO)(2){P(C4H4S)(3)}](6), along with an alkyne-bridged dicobalt complex, [Co-2(CO)(5)(mu-HCequivalent toCSiMe(3))-{P(C4H4S)(3)}](5), (5), were obtained as new compounds. The addition of the thienylphosphine ligand, in fact, facilitates the reaction rate. Reaction of an alkyne-bridged dicobalt complex, [(eta(2) -H-Cequivalent toC-SiMe3)Co-2(CO)(6)] (3), with a bi-functional ligand, PPh(-Cequivalent toC-SiMe3)(2), yielded an unexpected six-membered, cyclic compound, {[(Ph)(Me3Si-Cequivalent toC)P-[(eta(2)-Cequivalent toC-SiMe3)Co-2(CO)(5)]}(2)(7). (7). All of these new compounds were characterized by spectroscopic means; the solid-state structures of (5), (6) and (7) have been established by X-ray crystallography.en_US
