An organic-inorganic hybrid compound, [C6H5CH2CH2NH3]2[CdI4], exhibits a reversible ferroelectric phase transition at 301/297 K. Switchable dielectric constant, second harmonic generation, and pyroelectricity were synchronously observed accompanied by the order-disorder phase transition. This finding promotes research on molecular ferroelectrics to search for promising multifunctional switching materials at near room temperature.
