“…The understanding of phase transitions of these hybrid structures is quite important from materials point of view. In addition, these compounds exhibit numerous structural phase transitions related to reorientation motion in the organic part, [3][4][5][6][7] and so are classified to be of "order-disorder". Raman scattering investigations as a function of temperature present great interest since this indirectly brings information regarding molecular conformation and how the cations contribute to the mechanism of the phase transitions.…”

The Raman spectra of bis (4-acetylanilinium) tetrachloridozincate single crystals were studied in the range of 100-3500 cm −1 as a function of temperature of 298 K to 398 K. The bands mainly associated with the internal modes of the ZnCl 4 anions only undergo weak changes. However, the strong evolutions of wavenumbers, widths and intensities of many lines associated with the organic cations are observed with discontinuities in the vicinity of the phase transition at 351 K. A phase transition at Tc = 351K was observed and characterized by the differential scanning calorimetry (DSC). The most important changes are observed for two lines at 3197.13 cm −1 and 3167.10 cm −1 (at room temperature) issued from asymmetric and symmetric stretching vibrations of (C-H) band and (NH 3 ) group, respectively. The spectral characteristics of these lines are analyzed and consistently described in the framework of an order-disorder model for the phase transition. C 2015 Author(s).

“…The assumption that a free butylenediammonium cation, C NH 3 CH 2 spectra were assigned to the CH 2 stretching modes, as illustrated in Tables 1 and 3. Moreover, it was observed that the spectral regions corresponding to the NH and CH stretching modes were not too complex.…”

“…The assignments of the bands observed in the vibrational spectra of these compounds, and corresponding to the C NH 3 CH 2 n NH 3 C (n D 3 and 4) cations, were made by comparison with the vibrational spectra of other salts containing C NH 3 CH 2 n NH 3 C (n D 2, 3 and 4) cations 3 -13 along with those of NH 3 CH 2 5 NH 3 SnCl 6 . 2 With always the aim of extending our systematic studies of hexachlorostannate compounds containing alkylenediammonium cations and in order to understand better, in the future, the phase transitions of these compounds we present here a structural and vibrational study of two alkylenediammonium hexachlorostannate compounds, Vibrational spectra of alkylenediammonium hexachlorostannates belonging to the salt family described by the general formula NH 3 CH 2 n NH 3 MCl 6 . EXPERIMENTAL NH 3 CH 2 3 NH 3 SnCl 6 single crystals were obtained by slow evaporation, at room temperature, of a hydrochloric acid solution containing stoichiometric amounts of propylenediamine, NH 2 CH 2 3 NH 2 , (acidified with HCl) and SnCl 4 .…”

The infrared and Raman spectra of propylenediammonium hexachlorostannate, NH 3 (CH 2 ) 3 NH 3 SnCl 6 , and its butylenediammonium homologue, NH 3 (CH 2 ) 4 NH 3 SnCl 6 , were recorded at ambient temperature and interpreted on the basis of literature data. All the characteristics of the IR and Raman bands of anions and cations in these compounds were identified. The combination bands observed in the 2300-1900 cm −1 infrared spectral region for both compounds indicate that they contain C-NH 3 groups. Evidence for the existence of weak hydrogen bonds was found on examining the 2400-3200 cm −1 infrared spectral region. Thus, anions and cations are weakly connected by hydrogen bonding inside the crystals. The anions were found, in these two compounds, to be slightly distorted from their free O h octahedral symmetry.
