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(英文)

Syntheses, Crystal Structures and Antimicrobial Activities of Two Coordination Polymers Based on Bisbenzimidazole Ligands and V-Shaped Dicarboxylates

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)(H_2O)]·2H_2O}_n(1)和{[Mn_2(bbmb)(dcpe)_2(H_2O)]·1.5H_2O}_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。

Two coordination polymers {[Ni（bbmb）（dcpe）（H2O）]·2 H2O}n（1） and {[Mn2（bbmb）（dcpe）2（H2O）]·1.5 H2O}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.
