In the paper by Abrahams (2002![[Abrahams, S. C. (2002). Acta Cryst. B58, 34-37.]](../../../../../../logos/arrows/b_arr.gif "Abrahams, S. C. (2002). Acta Cryst. B58, 34-37.")
) Acta Cryst. (2002), B58, 34–37 two errors were printed. First, in the abstract the Curie temperature was incorrectly given as ∼1450 K. The correct value is ∼450 K. The second error occurs in section (a) of p. 36. The polar displacement expression is currently given as Δzl ≃ 1 Å. The correct expression should be Δzi ≃ 1 Å.
Keywords: ferroelectricity; spontaneous polarization; Curie temperature.
