AbstractTwo 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 μ2-η2:η1 bonding pattern leading to a 2D structure. Luminescent properties have been investigated in the solid state at room temperature.
