“…14. At a low temperature, the compound under study is a poor conductor (σ<10 −8 S/cm), whose slats conductivity quickly increases according to the Arrhenius law, up to a value of 1.99 × 10 −6 S/cm above 373 K. The Fig. 11 Temperature dependence of β value conductivity activation energies E p can be evaluated using the relation: [38] sT…”

The bis (3-dimethylammonium-1-propyne) pentachlorobismuthate (III) exhibits a structural phase transition at T 1 =(337±2 K), which has been characterized by differential scanning calorimetric, X-ray powder analysis, AC conductivity and dielectric measurements. The dielectric dispersion yielded the real and imaginary parts of impedance of (C 5 H 10 N) 2 BiCl 5 in the form of a semicircle in a complex plane. Besides, a Cole-Cole plot was observed at frequencies ranging from 209 Hz to 5 MHz, whose result was found to fit the theoretical resistor-capacitor parallel circuit model. The temperature dependence of the electrical conductivity in the different phases follows the Arrhenius law. The frequencydependent conductivity data were fitted in the modified power law: s ¼ s dc þ B 1 ðT Þw s 1 þ B 2 ðT Þw s 2 . The imaginary part of the permittivity constant is analyzed with the Cole-Cole formalism. With regard to the modulus plot, it can be characterized by full width at half height or in terms of a non-exponential decay function fðtÞ ¼ exp Àt. Besides, the activation energy responsible for relaxation has been evaluated and found to be close the DC conductivity.

“…The literature data on ion conduc tivity in these systems are very scantly. Previously, rel atively high ion conductivity was found in such salts as (C 2 H 5 ) 2 NH 2 Br, (C 3 H 7 ) 2 NH 2 Br [10], (C 3 N 2 H 5 ) 5 Bi 2 Cl 11 [11], tetramethylammonium dicyanamide [12,13], and 1 alkyl 2 methyl pyrrolidinium bistrifluoro methane sulfanylamides [14][15][16]. NMR studies showed that the appearance of appreciable ion con ductivity is accompanied by an increase in the reorien tational motion.…”

Based on the thermal and X ray diffraction analysis, NMR spectroscopy, and ion conductivity data it was shown that the organic salt [n Bu 4 N]BF 4 has an orientationally disordered phase with a primitive cubic unit cell (space group unit cell parameter a c = 1.4886(2) nm) in the temperature range 62-161°C. The mobility of molecular fragments and anions increased during the phase transition, and the ion conductivity was relatively high, reaching ~10 -6 S/cm at 150°C.

“…Recently, substantial attention has been carried on organicinorganic hybrid compounds due to their interesting nonlinear optical or polar properties (ferroelectric and ferroelastic) [1][2][3][4] and structural phase transitions [5][6][7][8]. It is well established that molecules containing ions such as Bi 3+ , Sb 3+ or Pb 2+ exhibit distorted structures due to the electrostatic effect of the lone pair of electron [9][10][11].…”

“…In fact, BiX 6 octahedra (X = halogen atom: Cl, Br and I) have a strong tendency to form isolated, dimeric, or polymeric anionic structure via connection by planes, edges, or corners. The most interesting compounds among the halogenoantimonates (III) and halogenobismuthates (III) salts appear to be the materials of general formula R a M b X 3b+a (where R denotes organic cation, M denotes the Sb or Bi metal, a and b are integer, and X denotes the halogen atom as Cl, Br or I) [1,3]. The simple molecular-ionic crystals have interesting properties as result of the features of the organic cations and the packing interactions.…”

The crystal structure of (C 5 N 2 H 7 ) 4 .HBi 2 Cl 11 has been determined at room temperature by single crystal X-ray diffraction. The compound crystallizes in the triclinic system with Pī space group. The crystal structure consists of two asymmetric inequivalent molecules of 4-aminopyridinium and anionic HBi 2 Cl 11 chains. The HBi 2 Cl 11 anionic chains stacked along the a-axis are formed with Bi 2 Cl 11 dimers connected to each other via hydrogen atoms. The crystal packing is stabilized with N-H...Cl hydrogen bonds connecting aminopyridinium units to the HBi 2 Cl 11 anionic chains. The title compound exhibits an order-disorder phase transition at 338 K. The AC electrical conductivity properties of (C 5 N 2 H 7 ) 4 . HBi 2 Cl 11 compound have been investigated by means of impedance spectroscopy measurements over wide ranges of frequencies and temperatures, 200 Hz to 5 MHz and 303 to 418 K, respectively. Detailed analysis of the impedance spectrum suggests that the electrical properties of the material are strongly temperature dependent. The frequency-dependent conductivity data were fitted in the Jonscher's law: s w ð Þ ¼ sð0Þ þ Aw n . The nature of variation of DC conductivity suggests Arrhenius type of electrical conductivity.
