Synthesis and chemical characterization of some transition metal complexes with a 6-acetyl-1,3,7-trimetyllumazine ligand

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,1h- and 13c-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. © 2017.
