A new mixed-ligand copper(II) complex of 1,10-phenanthroline and nitrate ligands [Cu(C 12 H 8 N 2 )(NO 3 ) 2 ] n is prepared and its crystal structure is determined by X-ray diffraction. The complex crystallizes in the monoclinic space group P21/ n , with unit cell dimensions a = 8.8226(3) Å, b = 9.1462(1) Å, c = 17.2507(4) Å, β = 101.680(2)°, Z = 4, V = 1363.19(6) Å 3 . The crystal structure is solved by the Patterson method and refined by full-matrix least squares treatment on F 2 to final values R 1 = 0.0447 and wR 2 = 0.1053. The Cu II ions are five-coordinated in a CuO 3 N 2 environment, giving a distorted square-based pyramidal geometry. The Cu…Cu distance in the [Cu(C 12 H 8 N 2 )(NO 3 ) 2 ] n zigzag polymeric chain is 5.258(1) Å. The structure of the title compound is polymeric and consists of layers running parallel to (10 1 ¯ ), interconnected by π–π interactions, strong enough to form a three-dimensional framework with tunnels along the a axis.
