What is it about?
X-ray diffraction is used to study the temperature dependence of the lattice parameters and the sequence of structural realignments in crystalline Rb2ZnCl4 over temperatures of 4.2–310 K. The appearance and changes in the system of satellite reflexes indicative of different structural ordering. Below 74 K, on going into the monoclinic phase.

Why is it important?
A reliable explanation for the sequence of phase transitions in crystalline Rb2ZnCl4 as a model object is important for understanding the behavior of the A2BX4 ferroelectric family.
Perspectives
A reliable explanation for the sequence of phase transitions in crystalline Rb2ZnCl4 as a model object is important for understanding the behavior of the A2BX4 ferroelectric family. Studies of the low-temperature phase IV, for which x-ray data are current lacking, require special attention. For this purpose, in this paper we have undertaken a systematic x-ray diffraction study of the configuration of the reciprocal lattice and measured the interplanar distances over a wide temperature range, 4.2 – 310 K.
