Crystal structure and fluorescence properties ofcatena-poly[[(2,2′-bi-1H-imidazole-κ2N,N′)cadmium]-di-μ-chlorido]

Abstract

In the polymeric title compound, [CdCl2(C6H6N4)]n, the central CdIIatom is coordinated by four chloride ligands and two N atoms from a chelating 2,2′-bi-1H-imidazole molecule, leading to a distorted octahedral Cl4N2coordination set. As a result of the μ2-bridging character of the Cl ligands, chains parallel to thecaxis 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.
