title: Decacarbonylbis(methylcyclopentadienyl)-tetrahedro-diiridiumdimolybdenum and decacarbonylbis(tetramethylcyclopentadienyl)-tetrahedro-diiridiumdimolybdenum dichloromethane hemisolvate.
abstract: The two title compounds, [Mo(2)Ir(2)(C(6)H(7))(2)(CO)(10)] and [Mo(2)Ir(2)(C(9)H(13))(2)(CO)(10)] x 0.5CH(2)Cl(2), respectively, or collectively [Mo(2)Ir(2)(mu-CO)(3)(CO)(7)(eta(5)-C(5)H(5-n)Me(n))(2)] (n = 1 or 4), have a pseudo-tetrahedral Mo(2)Ir(2) core geometry, an eta(5)-C(5)H(5-n)Me(n) group ligating each Mo atom, bridging carbonyls spanning the edges of an MoIr(2) face and seven terminally bound carbonyl groups.
