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 H-and 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
