The complex [CdI2(4-CNPy)(2)] (I) was obtained by a reaction of CdI2 with 4-cyanopyridine (4-CNPy, C6H4N2) and structurally characterized (CIF file CCDC no. 983377). The crystals of complex I are monoclinic, space group C2, a = 24.698(5) , b = 4.127(1) , c = 7.597(2) , beta = 96.05(1)A degrees, V = 770.0(3) (3), rho(calcd) = 2.477 g/cm(3), Z = 2. In structure I, iodine atoms serve to unite complex molecules into the polymer chains [CdI2(4-CNPy)(2)](a) along the direction [010]. The Cd(1) atom lying on a twofold axis has a slightly distorted octahedral environment made up of four bridging iodine atoms and two nitrogen atoms of two ligands 4-CNPy (Cd-I-av, 2.947(2) and Cd-N(1), 2.410(6) ). Within each chain, cadmium atoms are spaced apart at 4.13 . Complex I exhibits photoluminescence.
