Valence of Au in AuTe2 and AuSe studied by x-ray absorption spectroscopy

The gold compounds AuTe2 and AuSe contain Au atoms in two different chemical surroundings. In the literature these different coordinations have been associated with a difference in valency of the Au atoms. In this paper the occupation of the 5d shell in AuSe and AuTe2 is deduced from a study of the 4f → 5d X-ray absorption edge. A comparison is made with the absorption edges of Au, AuCl and AuCl3. The results show that only AuCl3 has Au atoms in a valence state of III, and that the Au atoms in AuTe2 and AuSe are all in the same monovalent state I, independent of their chemical environment.
