SrCrO3和聚偏氟乙烯之间的拓扑化学反应产生了新的氟化相SrCrO2.8F0.2。转化通过还原氧化物中间体（SrCrO2.8）进行，该中间体可以通过SrCrO3和g-C3N4之间的反应分离为单相。尽管SrCrO2.8具有氧空位有序结构，但氟离子随机占据阴离子位点。
A topochemical reaction between SrCrO3 and polyvinylydene fluoride yields the new fluorinated phase SrCrO2.8F0.2. The transformation proceeds via a reduced oxide intermediate (SrCrO2.8) 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 SrCrO2.8.
