Synthesis, Characterization and Crystal Structure of Mixed-Ligand Complex [Ni(PMBP-sal)(py)]

合成了混配配合物犤Ni(PMBP-sal)(py)犦,(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?配位形成略微畸变的平面正方形化合物。

A new mixed-ligand nickel W complex, [ Ni (PMBP-sal) (py)], (PMBP-sal = 1 -phenyl-3-methyl-4-benzylidene-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 the monoclinic system, space group P2(1)/c. The lattice parameters are: a = 1.3544 (3) nm, b = 1. 7225 (5) nm, c = 1.0937(2) nm, beta=102.57(2)degrees, V=2.4904(10) nm(3), D-cal = 1.462g . m(-3), Z = 4. The results show that the coordination geometry around nickel (11) in the ternary mixed-ligand complex is slightly distorted four-coordinated square-planar geometry, in which the primary ligand PMBP-sal participates in coordination with ONO donor atoms and the secondary ligand pyridine takes part in bonding with N donor atom.
