“…Among the organic–inorganic compounds, the halogenoantimonate(III) and halogenobismuthate(III) compounds with the general formula R a M b X 3 b+a (R = organic cation, M = Sb III or Bi III , and X = Cl, Br, or I) have recently been shown to be candidates for high‐temperature phase transitions . However, compounds with the R 3 [MX 5 ][X] chemical composition containing polyanionic chains have only been observed sporadically …”

A one-dimensional halogenobismuthate(III), [CMA] 3 ·[BiBr 5 ]· [Br] (1, CMA = cyclohexylmethylammonium), is discovered as a high-temperature phase-transition material with reversible and switchable dielectric behavior. Compound 1 undergoes a solid-state phase transition at T C = 401.6 K, as confirmed by differential scanning calorimetry (DSC), variabletemperature single-crystal X-ray diffraction, variable-temperature powder X-ray diffraction (PXRD), and dielectric measurements. Compound 1 crystalizes in the monoclinic space group P2 1 /c in the room-temperature phase (RTP). The asymmetric [a] Ordered

“…The origin of the ferroelectricity of either the R 3 M 2 X 9 or R 3 M 2 X 9 subclass is ascribed to the orientational disorder of dipolar organic cations as well as to the large electric polarizability of the anionic sublattice. The guanidinium halogenoantimonates(III) and halogenobismuthates(III) synthesized so far were found to crystallize with three different chemical compositions: R 2 MX 5 , R 3 M 2 X 9 and R 3 MX 6 [12][13][14]. Among them the compound characterized by the separated bioctahedral units M 2 X 3− 9 , namely Gu 3 Bi 2 Br 9 [15], appears to be the most interesting one.…”

Two novel guanidinium iodoantimonate(III) and iodobismuthate(III) crystals, [C(NH2)3]3[Sb2I9] and [C(NH2)3]3[Bi2I9], have been synthesized and their structures have been determined by means of single-crystal x-ray diffraction studies at three temperatures (293, 348 and 362 K). Both compounds appeared to be isomorphous in corresponding phases. The crystal structure of the title compounds is composed of discrete M2I93− (M = Sb, Bi) anions and C(NH2)3+ guanidinium cations. A non-equivalence of two guanidinium cations has been found. Both guanidinium analogs exhibit a rich sequence of phase transitions. In Gu3Sb2I9, three solid–solid structural phase transformations of the first order type are detected at 119/121, 341/344 and 355/362 K (on cooling/heating) by the DSC and dilatometric techniques. Gu3Bi2I9 displays four first order phase transitions: 179/185, 202/215, 287/291 and 358/368 K. The low temperature phases appear to have ferroic (ferroelastic) properties. The prototypic paraelastic phase for both compounds belongs to hexagonal symmetry (space group P63/mmc). The dielectric response has been measured in a wide frequency region (100 Hz–1 MHz), but no dielectric dispersion has been detected. Possible mechanisms of the phase transitions in Gu3M2I9 (M = Sb, Bi) are discussed on the basis of the presented results.

Bis(n-butylammonium) pentachloroantimonate(III) was obtained in a reaction of n-butylammonium chloride and antimony trichloride (molar ratio 2 : 1; cation : Sb) in acidic aqueous solution. To obtain further information about the mechanism of the earlier reported phase transitions at 229 and 315 K the structure was determined at 100, 260 and 340 K. The orthorhombic system was found in all phases, space groups Ibam at 340 K and Pccn at 260 and 100 K. In all phases the anionic sublattice consists of [SbCl 6 ] 3− octahedra, connected via cis chlorine atoms, forming onedimensional zig-zag {[SbCl 5 ] 2− } n chains extended along the c direction. The n-butylammonium cations are located between the inorganic chains, with -NH 3 + groups facing the oppositely charged polyanions. The phase transitions are of the order-disorder type. They are related to changes in molecular dynamics of the n-butylammonium cations. At high temperature the cations reorient, on decreasing temperature the reorientations are successfully frozen. This leads to the formation on N-H...Cl hydrogen bonds, which significantly deform the octahedral coordination of the Sb atoms.
