A 1-D Cd(II) Complex Based on 2-(1H-imidazole-1- ylmethyl)-1H-benzimidazole and 1,3,5- Benzenetricarboxylate

Abstract

A new complex, {[CdCl(H₂btc⁻)(imb)]·H₂O}_n (1), has been synthesized through the reaction of CdCl₂·2.5H₂O with ligands 2-(1H-imidazole-1-ylmethyl)-1H-benzimidazole (imb) and 1,3,5-benzenetricarboxylic acid (H₃btc) in water at 80°C. Single-crystal X-ray diffraction analysis shows that complex 1 exhibits 1-D double-stranded chain in which two Cd(II) ions are bridged by two carboxyl groups from two benzenetricarboxylates. These 1-D double-stranded chains are further stacked via hydrogen bonds and the π-π interactions leading to 3-D structure. A thermogravimetric analysis was carried out and the fluorescent property of the complex was investigated.
