Bis(ethylene)(η-pentamethylcyclopentadienyl)cobalt as a precursor to heteronuclear metal clusters: X-ray crystal strucutre of [Co2Mo2(µ-CO)3lpar;µ4-CO)(η-C5H5)2(η-C5Me5)2]; a model for CO activation on a stepped metal surface
Abstract
U.v irradiation of [Co(C2H4)2(η-C5Me5)] with the compounds [M2(CO)4(η-C5R5)2](M = Fe or Ru, and R = H; M = Fe, R = Me) or [Mo2(CO)4(η-C5H5)2] affords the clustesr complexes [CoM2(µ-CO)3(µ3-CO)-(η-C5Me5)(η-C5R5)2] and [Co2Mo2(µ-CO)3(µ4-CO)(η-C5H5)2(η-C5Me5)2]; the molecular structure of the latter species, established by X-ray diffraction, reveals a novel bonding mode for a CO ligand.
