From the direct reaction of ligands H(2)L(1) and H(2)L(2) with copper(II) and cobalt(II) salts in methanolic solution and in the presence of N(Et)(3) the neutral CuL(1), CuL(2), CoL(1) and CoL(2) complexes were prepared. All complexes were characterized by IR spectra, elemental analysis, magnetic susceptibility, mass spectra, molar conductance (Lambda(m)), UV-Vis spectra and in the case of CuL2 with X-ray diffraction. X-ray crystal structure of CuL2 showed that the complex contains copper( II) in a distorted square planar environment of N(2)O(2) donors. Three CH/pi interactions were observed in the molecular structure of latter complex. (C) 2008 Elsevier B.V. All rights reserved.
