Abstract

The description of the crystallographic structure of Cu complexes of intercalated compounds of α-Zr(HPO4)2·H2O (α-ZrP) reported in part I of this work is implemented with an X-ray photoelectron spectroscopy study performed on the same samples. The experiments carried out at room and liquid nitrogen temperatures, show, in contrast with data previously reported, that Cu2+ ions are reduced by the Al-Kα and Mg-Kα radiations. Nevertheless, some information on the electronic structure has been achieved for those elements that are not photoreduced. In particular, the N1s core line due to the interaction of nitrogen in the phenanthroline with hydrogen in the structure has been identified, and the suppression of this interaction with the increasing concentration of copper has been demonstrated.
