Abstract
The X-ray photoelectron spectra of several metal complexes of 2-mercaptobenzimidazole and 2-mercaptobenzoxazole were measured in order to examine the mode of coordination of the ligands. From their N(1s) and S(2p3⁄2) chemical shifts, it was suggested that the ligands are coordinated through both the sulfur and nitrogen atoms in most of the complexes.
