Synthesis and Structure Characterization of a 1D Chain Coordination Polymer[Zn(4,4′-bipy)(H_2O)_4]_n·(Paba)_(2n)

在水和乙醇的混合溶剂中合成了一维链状配合物[Zn(4,4′-bipy)(H2O)4]n·(Paba)2n(1)(4,4′-bipy=4,4′-联吡啶,PabaH=对氨基苯磺酸),并通过元素分析、IR和X-射线单晶衍射对其结构进行了表征。单晶衍射结果表明,配合物1属于单斜晶系,P2(1)/c空间群,晶胞参数:a=1.1273(4)nm,b=0.8306(3)nm,c=1.4380(5)nm,β=90.430(4)°,V=1.3464(8)nm-3,Z=2,Dc=1.574g.cm-3,μ=1.129mm-1,F(000)=660,R1=0.0382,wR2=0.0954,S=1.048。

A new chain coordination complex, namely [Zn（4, 4＇-bipy）（H2O）4]n · （Paba）2, （1） （PabaH= p-Amino-benzenesulfonic acid）, was prepared in water-ethanol solution. The crystal structure was deter- mined by elemental analysis, IR and X-ray diffraction. The results show that complex 1 crystallizes in monoclinic system with space group P2（1）/c and cell parameter a=1.1273（4）nm,b=0.8306（3）nm,c=1.4380（5）nm,β=90.430（4）°,V=1.3464（8）nm-3,Z=2,Dc=1.574g.cm-3,μ=1.129mm-1,F（000）=660,R1=0.0382,wRz2=0.0954,S=1.048.
