Dаtum izdаvаnjа: | 1-јул-2007 | Čаsоpis: | Journal of Inorganic Biochemistry | Sažetak: | A copper(II) complex with the pyridoxal-aminoguanidine (PL-AG) Schiff base adduct, as an organic compound of the very potent biological activity and promising pharmacological importance in the treatment of diabetic complications, has been prepared and characterized. The X-ray structural analysis of the [CuCl2(PL-AG)] complex showed that it has a distorted pseudo-square-pyramidal (4 + 1) structure with the tridentate ONN Schiff base in the equatorial plane, with the Cu-O(1), Cu-N(1) and Cu-N(3) bond lengths of 1.917(2) Å, 1.930(2) Å and 1.984(2) Å, respectively. The bond length of the equatorial Cu-Cl(1) is 2.279(1) Å, while that of the apical Cu-Cl(2) is 2.792(1) Å. Pyridoxal fragment is coordinated in its zwitterionic form. In addition to the X-ray structural analysis, the complex was characterized by IR spectrometric, conductometric and magnetic techniques, and the ligand itself by IR, 1H and 13C NMR spectra. © 2007 Elsevier Inc.
