The results of dielectric dispersion, dilatometric and infrared studies on a new member of the family of alkylammonium halogenoantimonates ([C(NH2)3]3Sb2Cl9) are presented. A dielectric dispersion was found in a broad temperature range from 150 to 100 K. The temperature characteristic of the electric permittivity, ϵ′, measured at a static frequency (1 kHz) suggests the presence of a phase transition at about 105 K. The dilatometric studies revealed only subtle changes in the expansion coefficient at this temperature. The infrared spectra in the temperature range 14–300 K do not show any distinctive changes. The results suggest that the guanidinium cations are stabilized in a crystal lattice by weak hydrogen bonds.
