The complexes [CuLCl2] (I), [CoLCl2] (II), and CuLBr2 (III) (where L is the derivative of optically active 5-pyrazolone prepared from the terpene (+)-3-carene) were obtained and characterized. According to X-ray diffraction data, crystal structures I and II (orthorhombic crystal system) are built from mononuclear acentric molecules. In the resulting complexes, the Cu2+ or Co2+ ion coordinates two N atoms of the chelating bidentate ligand L and two Cl atoms, thus making a distorted tetrahedron. Intermolecular contacts and the hydrogen bonds Cl(1)center dot center dot center dot H-O(1) give rise to columns parallel to axis y. For complexes I and III, mu(eff) = 1.83 and 1.81 mu B, respectively; these values correspond to the electronic configuration d(9). For complex II, mu(eff) = 4.42 mu B, which suggests the tetrahedral structure of the coordination entity CoCl2N2. Complexes I and III were studied by EPR spectroscopy.
