Abstract  

Complex formation reactions of copper(II) and zinc(II) halides with pyridoxilidene Girard-T hydrazone dihydrate [H3PLGT]Cl2·2H2O and salicylidene Girard-T hydrazone [H2SalGT]Cl ligands are described. The composition of the complexes, determined by customary methods, can be presented by the formulas Cu(HPLGT)X2 (X=Cl and Br ), Zn(HPLGT)Cl2, Cu(HSalGT)Cl2·H2O and Zn(SalGT)Cl·2H2O. The structures of the compounds were compared by powder X-ray diffraction. Thermal stability of the compounds has been examined by TG and DSC. The ligands and the complexes were tested against some gram-positive and gram-negative bacteria and yeast.
