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

Abstract

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.

Bicyclic 6-6 Systems: Pteridines

“…166 Polyhedral silver complexes of N,N,O-E- [6-(hydroxyimino)ethyl]-1,3,7-trimethyllumazine are also reported. 167 Transition metal complexes of the thiocarbazone 168 and pyridinylhydrazone 169 of 6-acetyl-1,3-7-trimethyllumazine were reported recently.…”

Theoretical, Voltammetric and Thermodynamic study for Cadmium(II)-Tyrosine Complex at 293-313 K

“…The physico-chemical properties of the complex have been evaluated using theoretical calculation, UV-Vis, thermo-gravimetric and IR were applied in the characterization of the interactions [20]. Also, the biological activity of the complexation of the adenine compound with numbers of transition metals have been carried out, theses metals were characterized and identification using conductivity, TGA and spectroscopic methods [21,22].…”

Biological Study of Transition Metal Complexes with Adenine Ligand

“…The interaction of nucleic acids and their constituents with metal ions has been a matter of extensive studies in the recent years, because of their chemical and biological interest, covering structural, thermodynamic and kinetic works. In this broad context, certain recent studies have focused on metal complexes that can specifically recognize nucleobases [2][3][4].…”
