邻苯二甲酸根桥联镍配位聚合物的合成与晶体结构

Synthesis and Crystal Structure of Phthalate Bridged Nickel Polymeric Complex

合成了邻苯二甲酸根桥联镍配位聚合物{ [ Ni(phth) (phen) (H2O) ]·H2O}n(phth:邻苯二甲酸根二价阴离子;phen: 1, 10-邻菲咯啉),并得到了它的单晶.用X射线单晶衍射法测定了配合物的晶体结构.

A phthalate nickel(Ⅱ)complex was synthesized , namely {\[Ni(phth)(phen)(H_2O)\] ·H_2O}_(n), where phth, phthalate; phen, 1,10-phenanthroline .The crystal structure of the complex was determined by single crystal X-ray diffraction , the result shows that the complex crystallizes in orthorhombic structure with space group Pca2_1, a=1.163 82 nm,b=1.116 13 nm,c=1.405 1(6) nm;Z=4,V=1.825 04(9) nm ~3,F(000)=904,Dc=1.598 Mg/m^3,μ=1.106 mm^(-1 ). The final R=(0.029 6),wR=0.072 9 based on 1 455 was observed by independent reflections with F_(0)>4σ(F_(0)) .X-ray analysis reveals that the moleculeis polymerizedwith extended phthalate bridges to form one-dimensional chain structure and the nickel(Ⅱ) ion is five-coordinated in a distorted square pyramid.
