Two new mononuclear complexes [Cu(Bzpy)2(Cl)2] (I) and [Cо(Bzpy)2(H2O)2](BF4)2 (II) are synthesized by the reactions of 2-benzoylpyridine (Bzpy) with the copper(II) and cobalt(II) salts. It is found by X-ray diffraction analysis (CIF files CCDC nos. 1908081 (I) and 1908080 (II)) that complex I is molecular and complex II is of the ionic type. Two neutral bidentate-chelate N,O-ligands Bzpy are coordinated to the complexing atom in both complexes. The Cl anions supplement the coordination polyhedra to octahedra in complex I, and the water molecules supplement the coordination polyhedra to octahedra in complex II. The [BF4] anions in complex II compensate the positive charge of the complex cations and are bound to them by intermolecular hydrogen bonds О–H···F along with electrostatic interactions.
