In order to continue our studies in coordination chemistry with pteridine derivatives, ligand pyridinylhdrazone of 6-acetyl-1,3,7-trimetyllumazine (PZLMH) and its mononuclear Cu(II), Ag(I), Cd(II), Hg(II) and Gd(III) complexes have been synthesized. Ligand and metal complexes were characterized by elemental analyses, 1 Hand 13 C-NMR and IR studies. The result ssuggest that the mononuclear complexes have a metal to ligand mole ratio of 1:1 and the metal ions are coordinated with the phenolic oxygen and imine nitrogen atoms.
