  Synthesis and characterization of a series of novel nickel(II)/nickel(I) complexes. Crystal structures of [NiCl2(dcpm)], [Ni(dcpm)2](NO3)2·2EtOH, [Ni2Cl2(μ-dcpm)2(μ-H)] and [Ni2(μ-PCy2)2(PCy2Me)2]; dcpm=bis(dicyclohexylphosphino)methane

  摘要：

  The complexes [(dcpm)NiCl(2)] (1), [Ni(2)Cl(2)(mu-dcpm)(2)(mu-H)] (3), [Ni(2)(mu-PCy(2))(2)(PCy(2)Me)(2)] (4) and [Ni(dcpm)(2)](NO(3))(2). 2EtOH (2), dcpm = bis(dicyclohexylphosphino)methane, have been prepared and characterized by (31)p, (1)H NMR (or EPR) as well as X-ray crystallography. The salt NiCl(2). 6H(2)O was found to react with dcpm to form the monomeric, four-coordinate, diamagnetic complex [(dcpm)NiCl(2)] (1). Compound 1 was then reduced with (n)Bu(3)SnH (or LiH with heating) in toluene at room temperature to form the air sensitive 'A-frame' complex [Ni(2)Cl(2)(mu-dcpm)(2)(mu-H)] (3). The Ni-Ni bond distance for 3 was found to be 2.904(3) A showing a lack of any Ni-Ni metal bonding. [Ni(2)(mu-PCy(2))(2)(PCy(2)Me)(2)] (4) was then formed by the reaction of 1 and excess LiH, heating to 90 degrees C in an oil bath. [Ni(2)Cl(2)(mu-dcpm)(2)(mu-H)] (3) was shown to be an intermediate in the synthesis of the bridging phosphido nickel complex. The Ni-Ni bond distance in 4 is 2.3910(8) Angstrom corresponding to a single Ni-Ni metal bond. The reaction of Ni(NO(3))(2). 6H(2)O with dcpm in ethanol yields the square planar complex [Ni(dcpm)(2)](NO(3))(2). 2EtOH (2). (C) 2000 Elsevier Science S.A. All rights reserved.
