铜基二维配位聚合物的合成及晶体结构表征

Synthesis and Crystal Structure Characterization of Copper-based Two-Dimensional Coordination Polymers

合成配位聚合物的一个行之有效的途径就是采用自发自组装的方法,藉助配位键和氢键的作用实现。本文以过渡金属离子铜(Ⅱ)为骨架离子,2,5-二羧基苯磺酸钠为主要配体,具有配位点的含氮有机化合物作为桥联配体,在有机溶剂体系中合成了具有二维网络结构的配位聚合物。合成的配合物为三斜晶体,空间群为P-1,晶胞参数:a=0.9961(14)nm,b=1.0116(15)nm,c=l.6960(2)nm;α=98.991(2)°,β=103.676(2)°,γ=103.302(2)°;V=1.5753(4)nm^3,Z=1,Dc=1.357mg·m^(-3),F(000)=610,R=0.0542,w R=0.1457,GOF=0.979。

One of the effective ways to synthesize the coordination polymer was to use self-assembly methods,with the aid of coordination and hydrogen bonding.The transition metal ions of copper(Ⅱ)were the central ions,2,5-dicarboxybenzenesulfonate as the main ligand,and the nitrogen-containing organic compounds with the coordination point as the bridging ligand.The coordination polymers with two-dimensional network structure were synthesized in the organic solvent system.The synthesized complex was triclinic,the space group was P-1,the unit cell parameter:a=0.9961(14)nm,b=1.0116(15)nm,c=l.6960(2)nm;α=98.991(2)°,β=103.676(2)°,γ=103.302(2)°;V=1.5753(4)nm3,Z=1,Dc=1.357mg/m3,F(000)=610,R=0.0542,wR=0.1457,GOF=0.979.
