[3,3-Difluorocyclobutylammonium]₂CrCl₄ is a Cr²⁺-based two-dimensional organic–inorganic hybrid perovskite that displays both ferroelectricity and ferromagnetism. It shows ferroelectricity with a high ferroelectric Curie temperature (T_c) up to 387 K and a saturate polarization of 2.1 μC cm⁻² and exhibits soft ferromagnet properties with a Curie temperature of 32.6 K.
