trans-Dichloridobis[(6-nicotinoyl-2-pyridyl-κN)(3-pyridyl-κN)methanone]copper(II)

Abstract

In the title complex, [CuCl(2)(C(17)H(11)N(3)O(2))(2)], the Cu(II) ion is located on an inversion center. It exhibits a distorted octa-hedral coordination geometry defined by two chloride anions at trans sites and four 3-pyridyl N atoms at equatorial sites from two (6-nicotinoyl-2-pyrid-yl)(3-pyrid-yl)methanone ligands. The (6-nicotinoyl-2-pyrid-yl)(3-pyrid-yl)methanone ligand can be viewed as having two pendant 3-pyridyl rings attached to a central pyridyl skeleton via separate carbonyl bridges, acting in a κ(2)N,N'-chelating mode with its 3-pyridyl N atoms bound to the Cu(II) ion. The pendant 3-pyridyl rings make a dihedral angle of 80.76 (5)°. In the crystal, mol-ecules are linked through inter-molecular C-H⋯π and C-H⋯O inter-actions, forming a three-dimentional framework.
