摘要:

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·nH2O(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,P21/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) nm3,Z=4,Dc=1.541 g/cm3,Mr=586.88,F(000)=1 208。 最终偏离因子R1=0.100 6,ωR2=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。

Abstract:

One mixedligand complex of [Zn(tpa)(tripy)]n·nH2O( 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 onoclinic crystal with space group P21/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) nm3,Z=4,Dc=1.541 g/cm3,Mr=586.88,F(000)=1 208. The complex consists of onedimensional Zigzag chain. Compared with the ligand, the complex exhibits intense photoluminescence.
