摘　　要：通过溶剂热合方法,制备了两种新的Zn^2+配位聚合物{[Zn(bib)(bdc)]·DMF}n(1)和{[Zn(bib)(bpdc)]·H2O}n(2)(bib=1,3-双(1-咪唑)苯,H2bdc=1,4-苯二甲酸,H2bpdc=4,4′-联苯二甲酸,DMF=N,N-二甲基甲酰胺)。通过单晶X-射线衍射确定了两个配合物的结构:配合物1属三斜晶系,空间群P-1,是一种由bib和ndc2-配体混合连接的二维网络结构;配合物2属单斜晶系,空间群P21/n,具有二重互穿二维网络结构。Two new Zn^2+coordination polymers{[Zn(bib)(bdc)]·DMF}n(1)and{[Zn(bib)(bpdc)]·H2O}n(2)(bib=1,3-bis(1-imidazolyl)benzene,H2bdc=1,4-benzenedicarboxylic acid,H2bpdc=biphenyl-4,4′-dicarboxylic acid and DMF=N,N-dimethylformamide)have been synthesized under solvothermal conditions and the structures were determined by single-crystal X-ray diffraction.Complex 1 crystallizes belongs to triclinic with P-1 space group,and is a 2D layer structure derived from bib and ndc2-mixed spacers.Complex 2 crystallizes belongs to monoclinic,space group P21/n,which is a 2-fold interpenetrated array based on 2D coordinated layers.
