  摘要：

  Reactions of the tetrahedral clusters Mo2Ir2(mu-CO)(3)(CO)(7)(eta(5)-L)(2) (L = C5H5, C5HMe4) with the molybdenum alkylidyne complex Mo( CC6H4OMe-4)(CO)(2){(N2C3H3)(3)BH-(KN)-N-3,N',N ''} afford the pentanuclear clusters Mo3Ir2(mu(4)-C)(mu(3)-CC6H4OMe-4)(mu-O)(CO)(6){(N2C3H3)(3)BH-kappa N-3,N',N ''}(eta(5)-C5H5)(2) (1; 62%) and Mo3Ir2(mu(3)-CC6H4OMe-4) (mu(3)-eta(2)-CO) (mu-CO) (CO)(6){(N2C3H3)(3)BH-kappa N-3,N',N ''}(eta(5)-C5Me4H)(2) (2; 65%), respectively, while the reaction of Mo2Ir2(mu-CO)(3)(CO)(7)(eta-C5H5)(2) with W( CC CSiMe3)(CO)(2){(N2C3H3)(3)BH-kappa N-3,N',N ''} yields the butterfly cluster Mo2Ir2(mu(4)-eta(2)-SiMe3C2C W(CO)(2){(N2C3H3)(3)BH-kappa N-3,N',N ''})(mu-CO)(4)(CO)(4)(eta(5)-C5H5)(2) (3; 60%). The identities of 1-3 have been confirmed by single-crystal X-ray diffraction studies. Cluster 1 contains mu(4)-carbido and mu-oxido ligands resulting from CO cleavage. Cluster 2, with sterically more encumbering tetramethylcyclopentadienyl ligands that arrest CO cleavage, possesses a mu(3)-eta(2)-CO ligand with a weak CO bond (1.272(7), 1.257(7) angstrom). Cluster 2 could not be converted into an analogue of cluster 1. The reaction with alkyne is more facile than the reaction with alkylidyne; cluster 3 results from addition of the C C bond (rather than the W C bond) across the Mo-Mo vector.
