摘要：

Long-term reaction of Cp2Mo(eta-2-CO2) (Cp = eta-5-C5H5) with HCo(CO)4 produces the novel hydride-bridged heterobimetallic complex Cp2Mo(mu-H)(mu-CO)Co(CO)3 (1) whose X-ray structure and bonding are described in detail. Complex 1 features a deficient electron count, a rare ''reverse'' unsymmetrical hydride bridge placing the hydride closer to the larger Mo atom [1.64 (3) angstrom vs 1.88 (3) angstrom to Co], and a close Mo-Co contact (2.8449 (4) angstrom). Analysis of 1 using extended Huckel calculations reveals that the metals bond to the hydride and carbonyl bridges in a four-center, four-electron bond. Despite the relatively short Mo-Co distance in 1, there is only a weak metal-metal bonding interaction.
