Abstract: Coordination compounds [CoLCl2] (I), [CuLCl(NO3)] (II), CuL(NO3)(2) (III), and CuLCl2 (IV) (where L is a chiral pyrazolylquinoline - a derivative of terpenoid (+)-3-carene) were synthesized. X-ray diffraction data showed that crystal structures I and 11 are built of mononuclear acentric molecules. In the molecule of complex 1, the Co2+ ion coordinates two N atoms of bidentate cycle-forming ligand L and two Cl atoms. The coordination polyhedron of Cl2N2 is a distorted tetrahedron. For complex I, mu(eff) = 4.50 mu(B), which corresponds to a high-spin configuration d(7). In the molecules of II(1), II(2) (which are diastereoisomers of complex II), each Cu2+ ion coordinates two N atoms of bidentate cycle-forming ligand L, the Cl atom, and two O atoms of bidenlate cyclic NO3- ion. The ClN2O2 coordination polyhedra are tetragonal pyramids with different degrees of distortion . The structure of complex II consists of supramolecular clusters, i.e., isolated chains incorporating the molecules of II(1) and II(2). The values of mu(eff) for II-IV correspond to the d(9) configuration. The results of EPR and IR study suggest that complex III contains the O4N2 polyhedron, whereas complex IV contains the Cl2N2 polyhedron. Complexes I and IV were found to show a high catalytic activity in ethylene polymerization reaction.
