Effect of some solvents, IR characterization and TGA investigation of complexes prepared by reactions between Arginine with some metal ions of Hg(II),Cd(II) and Mn(II)

Arginine complexes were prepared with some metal ions of Hg(II),Cd(II) and Mn(II) in a stoichiometric ratio of 1: 2 (Mn+: L), where Mn+ = Mn2+, Cd2+ and Hg+2 ions. The Complexes were characterized by the physicochemical and spectroscopic techniques as electric conductivity, metal contents, IR, UV–Visible, and molar conductance techniques. Thermal studies were carried out by thermo gravimetric analysis. The stoichiometric ratios of the synthesized complexes were confirmed by using molar ratio method. Solvent effect on the electronic spectra of the arginine ligand was examined using solvents with different polarities.
