Differential scanning calorimetry (DSC) was measured on (C_5H_5NH)_2[ZnBr_4], (C_5H_5NH)_2[CdBr_4], and (4-NH_2C_5H_4NH)_2[CdBr_4]･H_2O between about 130 K and their melting points. All of these compounds showed some structural phase transitions. Furthermore, these crystals exhibited some unusual DSC results. This paper reports on these unusual points.
