Above-room-temperature ferroelastic phase transition in a perovskite-like compound [N(CH3)4][Cd(N3)3]†
Abstract
A new perovskite-like compound [N(CH3)4][Cd(N3)3] is reported here, which undergoes a series of reversible phase transitions including an above-room-temperature ferroelastic phase transition. An order–disorder mechanism is found in these structural transitions owing to the sway of the rod-like N3− bridges as well as the rotation of the tetrahedron-like [N(CH3)4]+ guests.
