Synthesis and the Crystal Structure of [Ni(C_(15)H_(12)N_2O_3)(C_6H_7N)]

合成了含水杨醛缩苯氧基乙酰腙的镍的配合物[Ni(C15H12N2O3)(C6H7N)](C6H7N=α-甲基吡啶),通过X射线单晶衍射进行了表征。晶体属单斜晶系,空间群为P21/n,a=13.630(6),b=6.826(3),c=21.665(11),β=108.245(17)℃,V=1914.4(14)3,Z=4,Mr=420.10,Dc=1.458g.cm-3,μ=1.040mm-1,F(000)=872,R=0.0644,wR=0.1486。中心镍离子与水杨醛缩苯氧基乙酰腙配体提供的二个氧原子和一个氮原子以及一个配位α-甲基吡A°A°啶的氮原子配位,形成了N2O2的平面正方形的配位构型。在标题配合物中,水杨醛缩苯氧基乙酰腙三啮配体以负二价的阴离子形式存在。

The title nickel （Ⅱ）complex [Ni （L）（C6HTN）] with N-salicylaldehyde-N＇-phenoxyacyl hydrazone （H2L） has been prepared and characterized by X-ray single diffraction. The crystallographic data were as follows： monoclinic system, space p21/n, α=12.630（6）A^°,b=6.826（3）A^°,c=21.665（11）A^° ,β= 108.245（17）℃,V=1914.4（14） A^°^3,Z=4,Mr=420.10,Dc=1.459g＊cm^-3, μ=1.040mm^-1,F（000）=872,R=0.0644 and wR=0.1486. The Ni（ Ⅱ ） center is coordinated by three donors （two oxygen atoms and one nitrogen atom） from the ligand and one nitrogen atom from the coordinated α-methyl pyridine, forming a square-planar N2O2 coordination geometry. N-salicylaldehyde-N′-phenoxyacyl hydrazone acts as a dianionic tridentate ligand in the little complex.
