The cluster compound PrMo_7.6O₁₄

N. Barrier and P. Gougeon

Abstract: Praseodymium molybdenum oxide, PrMo_7.6O₁₄, is isostructural with LaMo_7.7O₁₄ and NdMo_7.7O₁₄. Their crystal structures derive from the NdMo₈O₁₄ type, which contains cis-edge-sharing bi-face-capped octahedral Mo₈ clusters. Because of the non-stoichiometry on the capping Mo sites and the absence of satellite reflections, Mo₆, Mo₇ and Mo₈ clusters are believed to co-exist randomly.
