Synthesis and Crystal Structure of [Ni(Phen)_3 Ni(DPC)_2]·11.5H_2O

以吡啶-2,6-二甲酸(H2DPC)和1,10-邻菲咯啉(Phen)为原料,首次合成了配合物[Ni(Phen)3][Ni(DPC)2].11.5H2O(1,C50H53N8Ni2O19.5),其结构经元素分析和X-射线表征。结果表明,1属单斜晶系,空间群为C2/c,晶胞参数为:a=29.863(3),b=14.971(2),c=24.638(3),β=104.800(10)°,V=10650(2)3,Z=8,S=0.883,Dc=1.491g.cm-3,μ=0.792mm-1,F(000)=4968。1由配阳离子和配阴离子通过静电引力结合而成,两个中心镍离子的配位多面体都是变形的八面体构型。

The complex, [ Ni （Phen） 3 ] [ Ni （DPC） 2 ]·11.5 H2O （ 1 ）, was synthesized by reaction of pyridine-2,6-dicarboxylic acid （ H2 DPC ）, 1,10-phenanthroline （Phen） and NiCl2·6 H2O. The crystal structure was characterized by X-ray diffraction and elemental analysis. The crystal belongs to monoclinic system, space group C2/c with α =29. 863（3） A, b = 14.971 （2） A, c =24. 638（3） A, β=104.800（10）°, V=10 650（2） A^3,Z=8 S=0.883,Dc=1.491g·cm^-3,μ=0.792mm^-1,F（000） =496 8. There is only a very weak interaction like static electricity exists between the anioncation in 1. The coordination geometry around two Ni （ Ⅱ ） are distorted octahedrons.
