Solid-to solid-state reversible phase transitions are widely used in switchable dielectrics, ferroelectrics, piezoelectrics, and pyroelectric and non-linear optical materials. Herein we report a new crown ether clathrate, [Habf-(18-crown-6) 1.5 ] + [PF 6 ] − (Habf = p -ammonium benzene formamide) wh...
