The article by Harding [(2002) Acta Cryst. D58, 872–874] is corrected.
Keywords: metal ligands; geometry; sodium and potassium.
In the first sentence of §4, Conclusions, of the article by Harding (2002) two numbers were accidentally interchanged. The sentence should start `Target distances for K+⋯O and Na+⋯O can be set (usually 2.84 and 2.42 Å, respectively; see Table 2a) for use as restraints or in validation…'. I am grateful to Professor Peter Artymiuk for pointing this out.
