Abstract:
This paper describes the synthesis of perovskite-like compound $\mathrm{Pb_2FeSbO}_6$ which undergoes a phase transition between 210–220 K. According to X-ray studies of the powder sample the structure of the initial cubic and the low-temperature tetragonal phases of $\mathrm{Pb_2FeSbO}_6$ were determined. The results obtained have been discussed using the group-theoretical analysis.
