Abstract

The XPS of solid complexes of ZnCl2/ZnSO4/ZnOAc2 with alpha-Met/His have been investigated. The results indicate that Zn2+ coordinate with O atom of carboxyl group and N atom of alpha-amino. The N atom of imidazolyl also participates the coordination. While the S atom of methylthio does not coordinate with Zn2+. This results are consistent with IR analyses. The structures of those complexes are presumed.
