Metal Complexes of Selenocysteamine

Abstract

In the reaction of selenocysteamine with nickel ion, formation of cationoid complex was confirmed by pH titration, elemental analysis, molar-ratio method and infrared spectra. On the basis of the formation of the cationoid complex, stability constants of cobalt, zinc, palladium and cadmium complexes of selenocysteamine were determined. In selenocysteamine, formations of the complexes were observed in more acid medium than in cysteamine.
