Streszczenie

The novel inorganic–organic hybrid material, allylammonium hexabromoantimonate(III), (C3H5NH3)3SbBr6, has been synthesized and its structure has been determined by means of the single-crystal X-ray diffraction studies at five temperatures (273, 248, 220, 170 and 100 K). At room temperature the compound crystallizes in the monoclinic space group, C2/m. Its crystal structure is composed of the discrete anions and three non-equivalent allylammonium, (C3H5NH3)+, cations. In (C3H5NH3)3SbBr6 three solid–solid structural phase transitions are detected: a continuous one at 260/256 K (on heating–cooling) from phase I to II, a discontinuous one at 227/208 K (II→III) and another discontinuous at 197/191 K (III→IV). The electric properties of the compound have been measured in a wide temperature region (150–300 K). Temperature-dependent vibrational properties in the frequency region 3500–500 cm−1 have been reviewed. Possible mechanisms of the phase transitions in (C3H5NH3)3SbBr6 are discussed on the basis of the presented results.
