title: Bis(imidazolium) L-tartrate: a hydrogen-bonded displacive-type molecular ferroelectric material.
abstract: A hydrogen-bonded ionic cocrystal with imidazole as molecular rotator and L-tartaric acid as homochiral component is reported as a displacive-type ferroelectric material. It undergoes a paraelectric-ferroelectric phase transition at 252 K with exceptional dielectric responses triggered by atomic displacements.
