合成了1个含N-乙酰基水杨酰肼(H3ashz)和咪唑(imdz)的三核镍(Ⅱ)配合物[Ni3(ashz)2(imdz)2].2DMF,并通过元素分析、红外光谱、紫外光谱、热分析以及X-射线单晶衍射等手段进行表征。结构分析结果表明标题化合物属于单斜晶系,P21/c空间群,晶胞参数为a=1.028 0(2)nm,b=1.499 2(3)nm,c=1.523 1(5)nm,β=114.16(2)°,V=2.140 1(9)nm3,Z=2,Dc=1.516 g.cm-3,μ=1.372mm-1,F(000)=1 012。配合物中,2个反式排列的五啮配体ashz3-的2个N-N肼基桥联3个Ni(Ⅱ)原子,形成了1个含Ni-N-N-Ni-N-N-Ni核心的直线型三核镍配合物,其中相邻Ni原子间距为0.462(1)nm。
A trinuclear nickel (Ⅱ) complex [Ni3 (imdz) 2] .2 DMF with N-acetylsalicylohydrazide (H3ashz) and imdz was synthesized and characterized by elemental analysis, UV spectroscopy, thermal analysis and X-ray single crystal diffraction and other means to characterize. The results of structural analysis indicate that the title compound belongs to the monoclinic space group P21 / c with unit cell parameters of a = 1.028 0 (2) nm, b = 1.499 2 (3) nm and c = 1.523 1 = 114.16 (2) °, V = 2.140 1 (9) nm3, Z = 2, Dc = 1.516 g.cm-3, μ = 1.372 mm-1, F (000) = 1 012. In the complex, two NN hydrazine groups of two trans arranged pentagonal ligands ashz3- bridged three Ni (Ⅱ) atoms to form a linear type with Ni-NN-Ni-NN-Ni core Trinuclear nickel complexes, in which the distance between adjacent Ni atoms is 0.462 (1) nm.
