An error in an equation in the paper by Song et al. [Acta Cryst. (2019), C75, 1353–1358] is corrected.

In the last equation of §2.2 (Expression for tolerance factor using ionic radius) of the paper by Song et al. (2019[Song, Z., Zhou, D. & Liu, Q. (2019). Acta Cryst. C75, 1353-1358.]), there is a typographical error in the numerator, which should be RA + RD, not RA - RD. The correct equation is given below:

[\eqalign{\tau &= {{L'}\over{H}} = {{2 \sqrt{ \left( R_B + R_D \right)^2 - \left( {{\sqrt 3}\over{3}} L \right)^2 } }\over{\sqrt{{{2}\over{3}}} \times \sqrt{{{8}\over{3}}} \left( R_C + R_D \right)}} \cr &= {{3 \sqrt{ \left( R_B + R_D \right)^2 - {{4}\over{9}} \left( R_A + R_D \right)^2 } }\over{ 2 \left( R_C + R_D \right)}}.}]
