Molecular–ionic crystals, which are built of organic cations and discrete anionic components with AMX4 stoichiometry, easily induce structural order–disorder transitions. These phenomena can generate interesting ferroic properties. Herein, we hav

Publikováno v: CrystEngComm 22(41), 6811-6821 (2020). doi:10.1039/D0CE00973C

Recently, interest in organic ferroelectrics or antiferroelectrics representing a metal-free perovskite-type has increased significantly. This interest results from the properties of organic systems. First of all, they do not have toxic metals in the

Multifunctional materials based on the double-perovskite organic–inorganic hybrid (CH3NH3)2[KCr(CN)6] showing switchable dielectric, magnetic, and semiconducting behaviour
