Crystal structure and fluorescence properties of catena-poly(22′-bi-1H-imidazole-κ2NN′)cadmium-di-μ-chlorido

摘要

In the polymeric title compound, [CdCl2(C6H6N4)]n, the central Cd^II atom is coordinated by four chloride ligands and two N atoms from a chelating 2,2′-bi-1H-imidazole mol­ecule, leading to a distorted octa­hedral Cl4N2 coordination set. As a result of the μ2-bridging character of the Cl ligands, chains parallel to the c axis are formed, with the chelating 2,2′-bi-1H-imidazole ligands decorated on both sides of the chain. The luminescence properties of the complex dispersed in di­methyl­formamide shows that the emission intensities are significantly quenched by nitro­benzene.
