Selected $2 \theta$ intervals for the four compositions of the $\mathrm{Sr}_{2} \mathrm{Co}_{1-x} \mathrm{Mg}_{x} \mathrm{TeO}_{6}$ series. a) Vanishment of the reflection that violates the I-centering condition on the $h k l$. b-c) Change of the cubic reflection splitting with the increase of the magnesium content.
