Cocrystal 55DMBP–H2ba was synthesized and characterized. The crystal structure is isostructural to cocrystal 55DMBP–H2ia with iodanilic acid. The heat capacity, dielectric permittivity, and polarization–electric field hysteresis showed that the 55DMBP–H2ba undergoes a paraelectric–ferroelectic phase transition at 253 K on cooling. The transition mechanism is discussed through the analysis of isotropic temperature factors of atoms.
