Abstract

A topochemical reaction between SrCrO₃ and polyvinylydene fluoride yields the new fluorinated phase SrCrO_2.8F_0.2. The transformation proceeds via a reduced oxide intermediate (SrCrO_2.8) that can be isolated as a single phase by the reaction between SrCrO₃ and g-C₃N₄. The fluoride ions randomly occupy anion sites despite an oxygen-vacancy ordered structure in SrCrO_2.8.
