Abstract

In the title complex, [CuCl2(C17H11N3O2)2], the CuII ion is located on an inversion center. It exhibits a distorted octa­hedral coordination geometry defined by two chloride anions at trans sites and four 3-pyridyl N atoms at equatorial sites from two (6-nicotinoyl-2-pyrid­yl)(3-pyrid­yl)methanone ligands. The (6-nicotinoyl-2-pyrid­yl)(3-pyrid­yl)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 κ2N,N′-chelating mode with its 3-pyridyl N atoms bound to the CuII ion. The pendant 3-pyridyl rings make a dihedral angle of 80.76 (5)°. In the crystal, mol­ecules are linked through inter­molecular C—H⋯π and C—H⋯O inter­actions, forming a three-dimentional framework.
