采用水热法合成了新的一维链状锌的配位聚合物[Zn(tpa)(tripy)]_n·nH_2O(tpa=对苯二甲酸,tripy=4′-(4-甲氧基苯基)-2,2′∶6′,2″-三联吡啶),通过红外光谱和元素分析对该配位聚合物进行了结构表征,用X射线单晶衍射测定了晶体结构. 结果表明,该配位聚合物属单斜晶系,P2_1/c空间群,a＝0.855 0(2) nm,b＝2.825 0(6) nm,c＝1.096 0(2) nm,β＝107.14(3)°,V＝2.529 7(9) nm~3,Z＝4,Dc＝1.541 g/cm~3,Mr＝586.88,F(000)＝1 208. 最终偏离因子R_1＝0.100 6,ωR_2＝0.264 8. 该化合物中Zn原子和2个对苯二甲酸酸根中的2个O原子和1个三联吡啶中的3个N原子配位. 相对于配体,该配位聚合物表现出明显增强的荧光发射性质.%One mixed-ligand complex of [Zn(tpa)(tripy)]_n·nH_2O( tpa=terephthalate, tripy=4′-(4-methyoxyphenyl)-2,2′∶6′,2″-terpyridine)] was synthesized and characterized by IR, elemental analysis and thermo-gravimetric analysis. The crystal structure of the product was established by single-crystal X-ray diffraction. It is a monoclinic crystal with space group P2_1/c. a=0.855 0(2) nm, b=2.825 0(6) nm, c=1.096 0(2) nm, β=107.14(3)°, V=2.529 7(9) nm~3, Z=4, Dc=1.541 g/cm~3, M_r=586.88, F(000)=1 208, R_1＝0.100 6, ωR_2=0.264 8. The complex consists of one-dimensional Zig-zag chain. Compared with the ligand, the complex exhibits intense photoluminescence.
