Abstract EN
Some metal complexes of DL-methionine were prepared in aqueous medium and characterized by different physico-chemical methods.
Methionine forms 1 : 2 complexes with metal, M (II).
The general empirical formula of the complexes is proposed as [(C5H10NO2S) 2M11]; where M11 = Mn (II), Co (II), Ni (II), Cu (II), Zn (II), Cd (II) and Hg (II).
All the complexes are extremely stable in light and air and optically inactive.
Magnetic susceptibility data of the complexes demonstrate that they are high spin paramagnetic complex except Zn (II), Cd (II) and Hg (II) complexes.
The bonding pattern in the complexes are similar to each other as indicated by electronic absorption spectra and FTIR spectral analysis.
The current potential data, peak separation (AE) and the peak current ratio (IPa / IPe) of the (Mn, Cu and Cd) complexes indicate that the charge transfer processes are irreversible, the systems are diffusion controlled and also adsorptive controlled.
The charge transfer rate constant of metals in their complexes are less than those in their metal salts at identical experimental conditions due to the coordination of metal with methionine.
