Synthesis and crystal structure of a trinuclear nickel (0) complex with 1,4-bis(trimethylsilyl)-1,3-butadiyne in the monodentate and μ2-ν2,ν2-bridging mode: [Ni3 (tmsb) (cod)3]

説明
A novel trinuclear nickel(0) complex [Ni3(tmsb) (cod)3] (cod = 1,5-cyclooctadiene) with 1,4-bis (trimethylsilyl)-1,3-butadiyne (tmsb) in the monodentate and μ2-ν2,ν2-bridging modes has been prepared and characterized crystallographically. The complex is triclinic, P1, a = 11.947(2), b = 15.407(3), c = 10.213(2) A, α = 96.47(2), β = 102.32(2), γ = 107.05(1) °, V = 1724.7(6) A3, Z = 2, R = 0.046 and Rw = 0.052. The acetylenic CC distance of 1.343(7) A in the μ2-ν2,ν2-bridging mode is considerably larger than that (1.267(7) A) in the monodentate mode. A weak v(CC) frequency was found at 1784 cm−1.
