基于双苯并咪唑及二羧酸配体配合物的合成、结构及抗菌活性

摘要

Two coordination polymers {[Ni(bbmb)(dcpe)(H2O)] ·2H2O}n (1) and {[Mn2(bbmb)(dcpe)2(H2O)]· 1.5H2O}n (2) have been synthesized utilizing a linear benzimidazole ligand 4,4'-bis (benzimidazol-1-ylmethy1)biphenyl) (bbmb) combined with a V-shaped dicarboxylates ligand 4,4'-dicarboxydiphenyl ether (H2dcpe).Compound 1 possesses a 2D thick layer structure with sql topology.Compound 2 possesses a 2D thick layer network with a linear tetranuclear Mn4 cluster within the network.The in vitro antimicrobial activities showed that both compounds have effective inhibiting effects.CCDC:1525542,1;1525543,2.%利用双苯并咪唑基配体4,4'-二(苯并咪唑-1-甲基)联苯(bbmb)与V形二羧酸配体4,4'-二羧苯基醚(H2dcpe)合成了配合物{[Ni(bbmb)(dcpe)(H2O)]·2H2O)n(1)和{[Mn2(bbmb)(dcpe)2(H2O)]· 1.5H2O)n(2).通过红外、元素分析、X射线单晶衍射、热重分析等检测手段对配合物结构进行了表征.配合物1是具有sql拓扑构型的二维层状化合物.配合物2呈现出含有四核锰构型的二维层状结构.体外抗菌实验证明2个配合物都表现出良好的抗菌活性.
