  Synthesis and crystal structure of unsymmetrical trinuclear nickel(0) complexes with the 1,3-butadiynes in the monodentate and μ2-η2,η2-bridgin mode [Ni3(L)(cod)3] (L= tmsb and dpbd)

  摘要：

  Novel trinuclear nickel(0) complexes [Ni-3(L)(cod)(3)] (cod = 1,5-cyclooctadiene) with L = 1,4-bis(trimethylsilyl)-1,3-butadiyne (1) and 1,4-diphenyl-1,3-butadiyne (2) have been prepared and their structures have been crystallographically determined. These trinuclear nickel(0) complexes are the first unsymmetrical trinuclear complexes with the 1,3-butadiynes in the monodentate and mu(2)-eta(2),eta(2)-coordination mode. The acetylenic C-C distance of 1.343(7) and 1.33(2) Angstrom for 1 and 2 in the mu(2)-eta(2),eta(2)-bridging mode is rather larger than that of 1.267(7) and 1.26(2) Angstrom for 1 and 2 in the monodentate mode, indicative of a larger contribution of pi back donation. The weak nu(C=C) frequency was given at 1784 and 1782 cm(-1) for 1 and 2, respectively.
