Article Abstract

Topochemical reduction of the = 1 Ruddlesden-Popper phases LaSrCoRhO and LaSrNiRhO with Zr yields LaSrCoRhO and LaSrNiRhO, respectively. Magnetization and XPS data reveal that while the rhodium centers in LaSrCoRhO and LaSrNiRhO have an average oxidation state of Rh, these are actually mixed valence Rh(I,III) compounds, with the disproportionation of Rh driven by the favorability of locating d Rh and d Rh cations within square-planar and square-based pyramidal coordination sites, respectively.
