Disorder-order ferroelectric transition in the metal formate framework of [NH4][Zn(HCOO)3].
A three-dimensional chiral metal formate framework compound, [NH(4)][Zn(HCOO)(3)], undergoes a paraelectric-ferroelectric phase transition at 191 K triggered by the disorder-order transition of NH(4)(+) cations within the structure.
