ABSTRACT: Two-dimensional organic-inorganic perovskites have been attracted as candidates for multiferroic materials that exhibit two or more ferroic orders such as ferromagnetism, ferroelectricity, ferroelasticity, and ferrotoroidicity. Here, we introduce the structure, ferroelastic domains and magnetic properties of the two-dimensional organic-inorganic perovskite [C6H9(CH2)2NH3]2FeCl4 (CHEA-Fe) composed of 2-(1-cyclohexenyl)ethylammonium and FeCl4 2-. CHEA-Fe underwent two ferroelastic phase transitions from tetragonal to orthorhombic at 332 K and to monoclinic at 232 K with decreasing temperature and exhibited ferroelastic domains under polarized light as a consequence of these ferroelastic phase t
