Study of Synthesis and Structure with a New Cadmium(Ⅱ)Complex

采用N,N-二甲基甲酰胺为溶剂,合成了新配合物[Cd_(3)L_(1)(L_(2))2(L_(3))3],[L_(1)=双(4-吡啶-4-苯基)胺][L_(2)=N,N-二甲基甲酰胺][L_(3)=对苯二甲酸],用元素分析和X射线单晶等进行了表征,结果表明该配位聚合物属于正交晶系,pbcn空间群,晶胞参数:a=11.7865(19)nm,b=11.716(3)nm,c=1.3300(2)nm,F(000)=5160,D=1.665 g/cm^(3),V=10.421(3)nm^(3),Mr=1298.14,Z=8,μ=1.283 mm^(-1),R_(1)=0.0689,wR=0.1549。该配合物中Cd(Ⅱ)采用三种不同的配位方式形成三维晶体结构。

A new complex[Cd_(3)(L_(1))(L_(2))2(L_(3))3],[L_(1)=bis(4-pyridine-4-phenyl)amine][L_(2)=N,N-dimethylformamide][L_(3)=terephthalic acid]was synthesized by solvothermal method with N,N-dimethylformamide.The complex was analyzed by elemental analysis and XRD.The results show that the coordination polymer belongs to the space group of orthogonal crystal system pbcn,and the cell parameters are:a=11.7865(19)nm,b=11.716(3)nm,c=1.3300(2)nm,F(000)=5160,D=1.665 g·cm^(3),V=10.421(3)nm^(3),Mr=1298.14,Z=8,μ=1.283 mm^(-1),R_(1)=0.0689,wR=0.1549.The complex forms a three-dimensional supramolecular structure through coordination mode with three kinds of Cadmium(Ⅱ).
