چکیده
In the polymeric title compound, [CdCl2(C6H6N4)] n , the central CdII atom is coordinated by four chloride ligands and two N atoms from a chelating 2,2'-bi-1H-imidazole mol-ecule, leading to a distorted octa-hedral 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 di-methyl-formamide shows that the emission intensities are significantly quenched by nitro-benzene.
