Abstract
Single crystals of general molecular formula ABX3, where A is a monovalent ion (A+) equals Tl+, Cs+), B is a divalent element (B2+ equals Cd2+, Pb2+), and X equals Cl/Br, belong to an important class of halide crystals that attract attention of investigators due to their interesting properties and various phase transition mechanisms. Some structure sensitive and acousto-optical parameters were obtained from the experimental results. The temperature behavior of the dielectric permittivity and conductivity of these insufficiently investigated crystals in the range 250 - 550 K corresponds to a normal behavior of ionic crystals. It was found that the correlation took place between a tolerance- factor and some structure sensitive parameters of the above- mentioned crystals.
