Temperature evolution of the cell parameters of $\operatorname{SrPr} M \mathrm{MuO}_{6}(M=\mathrm{Zn}, \mathrm{Mg}, \mathrm{Ni})$ as obtained from the NPD data (HRPT $\lambda=1.494 \AA(\mathrm{Zn}, \mathrm{Ni}), \mathrm{D} 2 \mathrm{ B} \lambda=1.594 \AA(\mathrm{Mg}))$: cell parameters for the monoclinic and trigonal phases. For comparison the parameters have been scaled as indicated by the legends.
