Abstract

Three cadmium complexes incorporating both aliphatic α,ω-dicarboxylate and 2-(1H-imidazol-1-methyl)-1H-benzimidazole (imb) have been prepared and structurally characterized. [Cd2Cl2(suc)(imb)2(H2O)]n (1) manifests 2D layered structure built from the linkage of tetranuclear [Cd4Cl4(suc)2(H2O)2] units through two kinds of imb ligands. {[Cd(glu)(imb)]·H2O}n (2) contains ladderlike [Cd(glu)]n chains which are bridged by imb ligands to form the 2D layers. {[Cd2Cl2(adi)(imb)2]·2H2O}n (3) also displays 2D network in which dinuclear units [Cd2Cl2] were linked by imb ligands to form double-stranded chains and these chains were further linked by adi2− ligands. Results indicate that aliphatic dicarboxylate ligands play an important role in governing the formation of final frameworks. Additionally, IR spectra, PXRD patterns, TG analyses and fluorescent properties of certain complexes have been determined.
