Simulated X-ray diffraction patterns for ordered \left(A A^{\prime}\right) B B^{\prime} \mathrm{O}_{6} cubic structure (black) and the most common distorted symmetries: R \overline{3} (red), I 4 / m (green), I 2 / m (blue) and P 2_{1} / n (purple). In the inset is shown the splitting of the peaks. (Simulation characteristics: \lambda=1.5406 \AA (XRPD), a_{\mathrm{p}}=3.8873 \stackrel{\circ}{\mathrm{A}}, F m \overline{3} m\left(a=2 a_{\mathrm{p}}\right), R \overline{3}\left(\mathrm{a} \approx \sqrt{2} a_{\mathrm{p}}, \mathrm{c} \approx 2 \sqrt{6} a_{\mathrm{p}}\right), I 4 / m\left(a=\mathrm{b} \approx \sqrt{2} a_{\mathrm{p}}, \mathrm{c} \approx 2 a_{\mathrm{p}}\right), I 2 / m and P 2_{1} / n\left(\mathrm{a} \approx \mathrm{b} \approx \sqrt{2} a_{\mathrm{p}}\right., \mathrm{c} \approx 2 a_{\mathrm{p}}, \beta \approx 90^{\circ}).)
