Undecacarbonyl(methylcyclopentadienyl)-tetrahedro-triiridiummolybdenum, undecacarbonyl(tetramethylcyclopentadienyl)-tetrahedro-triiridiummolybdenum and undecacarbonyl(pentamethylcyclopentadienyl)-tetrahedro-triiridiummolybdenum.
The three title compounds tri-mu-carbonyl-1:2kappa2C;1:3kappa2C;2:3kappa2C-octacarbonyl-1kappaC,2kappa2C,3kappa2C,4kappa3C-eta5-methylcyclopentadienyl-tetrahedro-triiridiummolybdenum(3 Ir-Ir)(3 Ir-Mo), tri-mu-carbonyl-1:2kappa2C;1:3kappa2C;2:3kappa2C-octacarbonyl-1kappaC,2kappa2C,3kappa2C,4kappa3C-eta5-tetramethylcyclopentadienyl-tetrahedro-triiridiummolybdenum(3 Ir-Ir)(3 Ir-Mo) and tri-mu-carbonyl-1:2kappa2C;1:3kappa2C;2:3kappa2C-octacarbonyl-1kappaC,2kappa2C,3kappa2C,4kappa3C-eta5-pentamethylcyclopentadienyl-tetrahedro-triiridiummolybdenum(3 Ir-Ir)(3 Ir-Mo), [MoIr(3)(eta5-C(5)H(5-n)Me(n))(mu-CO)(3)(CO)(8)], where n = 1, 4 or 5, have a pseudotetrahedral MoIr(3) core geometry, with a eta5-C(5)H(5-n)Me(n) group ligating the Mo atom, bridging carbonyls spanning the edges of an MoIr(2) face, and eight terminally bound carbonyls.
