space group). The atomic arrangement can be described by an alternation of two types of organic–inorganic layers stacked in [010] direction. The nature of the inorganic polyhedra distortion which can be attributed to the stereo activity of the Bi(III) lone electron pair has been studied. Regarding the differential scanning calorimetry, it disclosed one structural phase transition at Tu2009=u2009423 (±5)u2009K of the order–disorder type. Furthermore, the dielectric properties of the compound were studied using complex impedance spectroscopy in the frequency range 209xa0Hz–5xa0MHz and temperature range 368–458xa0K. The frequency-dependent AC conductivity is well described by Jonscher’s universal power law. The nature of DC conductivity variation suggests Arrhenius type of electrical conductivity.

Chemical preparation, mid-infrared and Raman spectra of [N(C(3)H(7))(4)](2)Cd(2)Cl(6) are presented. Polarized Raman spectra of oriented single crystals have been recorded in the range 7-3900 cm(-1) under various polarization configurations with regard to the symmetry and the numbers of several band modes observed in the Raman and infrared spectra. The obtained results are consistent with the theoretical predictions based on the infrared and Raman selection rules.
