Аннотация

A new mixed-ligand copper(II) complex of 1,10-phenanthroline and nitrate ligands [Cu(C12H8N2)(NO3)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) Å3. The crystal structure is solved by the Patterson method and refined by full-matrix least squares treatment on F 2 to final values R1 = 0.0447 and wR2 = 0.1053. The CuII ions are five-coordinated in a CuO3N2 environment, giving a distorted square-based pyramidal geometry. The Cu…Cu distance in the [Cu(C12H8N2)(NO3)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 (101), interconnected by π-π interactions, strong enough to form a three-dimensional framework with tunnels along the a axis.
