Crystal structures and luminescence properties of two Cd(II) complexes based on 2-(1H-imidazol-1-methyl)-6-methyl-1H-benzimidazole

Abstract

Abstract Two new complexes, {[Cd(immb)I2]·DMF} n (1) and {[Cd3(immb)(btc)2]·H2O} n (2) (immb = 2-(1H-imidazol- 1-methyl)-6-methyl-1H-benzimidazole, btc = 1,2,3-benzenetricarboxylate, DMF = dimethyl formamide), have been synthesized and characterized. Single crystal X-ray diffraction shows that 1 exhibits a chain structure constructed by immb ligands bridging Cd(II) ions. In 2, Cd(II) ions are linked by immb ligands with bridging mode and btc3– anions with the μ 2-η 2:η 1 bonding pattern leading to a 2D structure. Luminescent properties have been investigated in the solid state at room temperature.
