Abstract

The reaction between 3-hydroxy-5-hydroxymethyl-2-methyl-4- pyridinecarboxaldehyde semicarbazone (pyridoxal-semicarbazone or PLSC) and appropriate chloride, sulfate, nitrate or thiocyanate Cu(II) salts in water/alcohol mixtures resulted in the formation of new copper(II) complexes: [Cu(PLSC)Cl2] (1), [Cu(PLSC)(H2O)(SO4)] 2·3H2O (2), [Cu2(PLSC) 2(NCS)2](NCS)2 (3), [Cu(PLSC)(NO 3)2(CH3OH)] (4) and [Cu(PLSC-2H]NH 3·H2O (5). The complexes were characterized by elemental analysis, conductometric measurements and IR spectroscopy, while complexes 1, 2, 3 and 4 were further characterized by single crystal X-ray diffraction.
