a): Amplitudes of $\mathrm{GM}_{4}^{+}, \mathrm{X}_{3}^{+}$and $\mathrm{X}_{5}^{+}$irreps consolidating the RT phases of $\mathrm{Sr}_{2} \mathrm{MSbO}_{6} \mathrm{M}=\mathrm{Ln}$ (Nd, Eu, Gd, Dy, Ho, Er, Tm, Yb and Y materials in the monoclinic symmetry $P 2_{1} / n$, as function of the tolerance factor. The red balls stand for the $\mathrm{Sr}_{2} \mathrm{YSbO}_{6}$ amplitudes, since the Yttrium, Y, does not belong to the Lanthanides. b): Two dimensional section showing the obtained amplitudes of the irreps (Blue) $\mathrm{GM}_{4}^{+}$, $(R e d) \mathrm{X}_{3}^{+}$and the two components of the tri-dimensional $\mathrm{X}_{5}^{+}$: A10 in $x$-axis and A11 in $y$.
