以Schiff碱N-丁酰基水杨酰肼为配体的三核镍(Ⅱ)配合物的合成与结构
The trinuclear nickel (Ⅱ) complex Ni3(C11H11N2O3)2(C5H5N)4 was prepared by the reaction of Ni(OAc)2 @ 4H2Owith N-butylsalicylhydrazide Schiff base ligand and characterized by X-ray crystallography. The crystal belongs totriclinic, Mr=930.91, space group P1 with cell parameters a =9. 8489(2)A, b = 12. 3110(2) A, c = 18. 4035(3) A, α=71.353(2)°, β=76.638(2)°, γ=84.815(2)°, V=2056.72(6)A3, Z=2, Dc=1.503g@cm-3,μ(MoKα) = 1. 417mm-1, F(000) = 964, R = 0. 0317, wR = 0. 0868. A total of 5393 independent reflectionswere collected, of which 4448 reflections with I ≥ 2 σ(I) were observed. There are two centrosymmetrical trin-angle of 180°. The interatomic distances between the nickel atoms on the two sides are 9. 2030(8) A and 9. 1876(9) A for the two molecules, respectively. The central nickel atom adopts an axially elongated octahedral geometrywhereas the nickel atoms on the two sides have square-planar coordination environment. CCDC: 194083.
