Fig. 5: Overview of the rich low-temperature sulfur topochemistry in the La–O–S system.
From: Design of metastable oxychalcogenide phases by topochemical (de)intercalation of sulfur in La2O2S2
The topochemical intercalation and deintercalation of sulfur in the oxychalcogenide compound La2O2S2 lead to the formation of two new metastable compounds.
