摘要
在溶剂热合成条件下得到2个单一手性配位聚合物,即[Cd3((R)-CIA)2(bipy)2.5(H2O)2]·xGuest(1)和[Zn3((R)-CIA)(bmib)2(H2O)2 Cl]·H2O·xGuest(2)((R)-H3CIA=(R)-5-(1-羧基乙氧基)间苯二甲酸,bipy=4,4′-联吡啶,bmib=1,4-双(2-甲基-1H-咪唑-1-基)苯)。X射线单晶结构分析揭示配合物1和2都是柱层式结构的三维框架。从拓扑分析的角度看,配位物1具有(3,3,3,6,6)-连接的网络,拓扑符号为(4.5^2)2(4.8^2)2(42.6^8.8^3.10^2)(4^2.6^8.8^3.9^2)(5.8.9)2,而配合物2是(3,4,4)-连接的网络,拓扑符号为(6·7^2)2(6·7^5)2(6^2·7^4)。此外,对上述配合物的热稳定性、圆二色谱和荧光性质也做了研究。
Two homochiral coordination polymers[Cd3((R)-CIA)2(bipy)2.5(H2O)2]·xGuest(1)and[Zn3((R)-CIA)(bmib)2(H2O)2Cl]·H2O·xGuest(2)((R)-H3CIA=(R)-5-(1-carboxyethoxy)isophthalic acid,bipy=4,4′-bipyridine,bmib=1,4-bis(2-methyl-1H-imidazol-1-yl)benzene)were obtained under solvothermal reaction conditions.X-ray single crystal structure analysis reveals that complexes 1 and 2 are all 3D pillar-layered frameworks.From the viewpoint of structural topology,complex 1 possesses a(3,3,3,6,6)-connected net with a point symbol of(4.5^2)2(4.8^2)2(4^2.6^8.8^3.10^2)(4^2.6^8.8^3.9^2)(5.8.9)2,while complex 2 is a(3,4,4)-connected net with a point symbol of(6·7^2)2(6·7^5)2(6^2·7^4).Moreover,thermal stabilities,CD spectra and luminescent properties of these new complexes have been studied.CCDC:1920451,1;1920452,2.
