摘　　要：以1,4-双(2-甲基苯并咪唑-1-亚甲基)苯(bmb)和2个芳香多羧酸1,2,4,5-均苯四酸(H4btec)、4-(3,4-二羧基苯甲酰)邻苯二甲酸(H4dcbp)为配体,在水热条件下合成了2个锌配位聚合物{[Zn(bmb)0.5(btec)0.5(H2O)]·H2O}n(1)和{[Zn2(bmb)2(dcbp)]·5H2O}n(2),并用X射线单晶衍射、红外光谱、元素分析和粉末衍射对其结构进行了表征。晶体结构测试表明2个聚合物均为复杂的三维框架结构,配体bmb在2个配合物中均为μ2-η1∶η1的配位模式。此外还研究了2个配合物的荧光性质和热稳定性。Two new coordination polymers,{[Zn(bmb)0.5(btec)0.5(H2O)]·H2O}n(1)and{[Zn2(bmb)2(dcbp)]·5H2O}n(2)were synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffractions,IR spectra,elemental analyses and powder X-ray diffractions(bmb=1,4-bis(2-methylbenzimidazol-1-ylmethyl)benzene,H4btec=1,2,4,5-benzenetetracarboxylic acid,H4dcbp=4-(3,4-dicarboxybenzoyl)phthalic acid).Structural analyses reveal that both polymers 1 and 2 exhibit complicated 3D frameworks in which bmb acts as linker withμ2-η1∶η1 coordination mode.Thermal stabilities and solid-state luminescence at room temperature of 1 and 2 also were investigated.
