We report herein new oxides and oxyfluorides built on the apatite crystal framework and hosting Mn5+, a rare oxidation state of manganese, very scarcely observed in oxides. We take the opportunity of isolating these new solids to provide the first spectroscopic characterization of Mn5+ by EELS and to show the significant ionic conductivity of these solids.
This work was hosted by the department of Solid State Chemistry of the Universidad Complutense de Madrid. A strongly collaborative work with the RMES group of LCMCP lab, the Solid-State Chemistry and Energy Lab at Collège de France, and ILL at Grenoble.
