Abstract

In this work the covalent anchoring of C-protected Cu(II)-l-cysteine and Cu(II)-l-cystine complexes onto a surface-modified silica gel is described. Conditions of the syntheses were varied and the obtained structures were studied by classical analytical (titration) as well as spectroscopic (infrared, atomic absorption) methods. It was found that the sulphur atoms in the molecules acted as primary coordination sites, while the other coordinating groups varied depending on whether the complexes were formed under ligand-poor or ligand-excess conditions.
