  Structural Factors Influencing Linear M−H−M Bonding in Bis(dialkylphosphino)methane Complexes of Nickel

  摘要：

  Structural data for four closely related dinuclear nickel hydride complexes have been compared in order to gain insight into the factors governing the Ni-H-Ni geometries. The derivatives [( dippm)(2)Ni2X2]( A-H) [ dippm) 1,2-bis( diisopropylphosphino)methane] were found to contain a linear Ni - H - Ni bridge, whereas the derivatives [( dcpm)(2)Ni2X2]( mu-H) [ dcpm) 1,2-bis( dicyclohexylphosphino)-methane] were found to contain a bent Ni - H - Ni bridge. The number of internal and interatomic CH-to-halide contacts of the former were much shorter and more numerous than the latter, suggesting an important role of external forces in bridging hydride geometries.
