A new mixed-ligand nickel (Ⅱ) complex, [Ni(PMBP-sal) (py)], (PMBP-sal = 1-phenyl-3-methyl-4-benzylid-ene-pyrazolone-5) salicylhydrazone; py = pyridine), has been synthesized and characterized by elemental analysis,IR spectrum, UV-visible spectrum, cyclic voltammogram and single crystal X-ray diffraction. It crystallizes in themonoclinic system, space group P21/c. The lattice parameters are: a = 1. 3544(3) nm, b = 1. 7225(5) nm, c =1. 0937(2) nm, β= 102.57(2)°, V=2. 4904(10) nm3, Dcal = 1. 462g @ m-3, Z =4. The results show that thecoordination geometry around nickel (Ⅱ) in the ternary mixed-ligand complex is slightly distorted four-coordinatedsquare-planar geometry, in which the primary ligand PMBP-sal participates in coordination with ONO donor atomsand the secondary ligand pyridine takes part in bonding with N donor atom. CCDC: 173586.%合成了混配配合物[Ni(PMBP-sal)(py)],(PMBP:1-苯基-3-甲基-4-苯亚甲基吡唑啉酮-5,sal:水杨酰肼,py:吡啶),并用元素分析,IR光谱,紫外可见吸收光谱,循环伏安和单晶x-射线衍射进行表征.结构分析表明N-(1-苯基-3-甲基-4-苯亚甲基吡唑啉酮-5)-水杨酰肼和吡啶与Ni(Ⅱ)配位形成略微畸变的平面正方形化合物.
