A new ferroelastic hybrid material with a large spontaneous strain: (Me3NOH)(2)[ZnCl4]

abstract

A new hybrid compound (Me3NOH)(2)[ZnCl4] undergoes an above-room-temperature mmmF2/m ferroelastic phase transition and exhibits a large spontaneous strain of 0.129, owing to an order-disorder transition of organic cations.
