Metal complexes with girard reagents-based ligands: Part II. Copper(II) and zinc(II) complexes with pyridoxilidene and salicylidene Girard-T hydrazone

Complex formation reactions of copper(II) and zinc(II) halides with pyridoxilidene Girard-T hydrazone dihydrate [H 3 PLGT]Cl 2 •2H 2 O and salicylidene Girard-T hydrazone [H 2 SalGT]Cl ligands are described. The composition of the complexes, determined by customary methods, can be presented by the formulas Cu(HPLGT)X 2 (X=Cl - and Br - ), Zn(HPLGT)Cl 2 , Cu(HSalGT)Cl 2 •H 2 O and Zn(SalGT)Cl• 2 H 2 O. 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. © 2006 Springer-Verlag.
