Symmetry-breaking phase transitions, dielectric and magnetic properties of pyrrolidinium-tetrahalidocobaltates

We report the physicochemical analysis of Co-based pyrrolidinium analogues: (C 4 H 10 N) 2 CoCl 4 and (C 4 H 10 N) 2 CoBr 4 . The results confirm that introducing mobile organic cations into an inorganic network might construct compounds with multiple properties.
