摘要
A novel trinuclear nickel（II） complex [Ni3（bushz）z（Himdz）2（H20）2].2DMF （1, bushz = N-butylsalicylhydrazide, Himdz = imidazole, DMF = N,N-dimethyl-forrnamide） has been synthesized and characterized by X-ray single-crystal diffraction characterization. Complex 1 crystallizes in the monoclinic system, space group P2 1/c with a = 7.706（7）, b = 14.882（6）, c = 18.639（6） A, β = 108.08（2）°, V= 2032（1） A3, Dc = 1.525 g/cm3, Mr = 932.95, Z= 2, F（000） = 972,μ = 1.442 mm-1, the final R = 0.0359 and wR = 0.0771. The three nickel（II） atoms in 1 are arranged in a strictly linear structure and exhibit alternating square-planar and octahedral geometries. The complex is connected to form a supramolecule with an infinite three-dimensional network through intermolecular hydrogen bonds. The electrochemical studies reveal that redox of Ni3＋/Ni2＋ in the complex is a quasi-reversible process. The thermal stability of the title complex was also studied.
