(Received 19 February 2008; accepted 19 February 2008; online 22 February 2008)

Corrections are made to the formulation and scheme in Tombul, Güven & Büyükgüngör [Acta Cryst. (2007) E63, m1783–m1784].

The structure reported by Tombul, Güven & Büyükgüngör [Acta Cryst. (2007) E63, m1783–m1784] was incorrectly formulated. The compound is actually poly[diaqua(μ2-3-carboxypyrazine-2-carboxylato)(μ2-pyrazine-2,3-dicarboxylic acid)caesium(I)], [Cs(C6H3N2O4)(C6H4N2O4)(H2O)2]n. A disordered H atom was omitted in the structural analysis, which leads to protonation of half the organic ligands and corrects the charge imbalance of the original structure. The compound is isostructural with the corresponding potassium complex, which is fully described by Tombul, Güven & Svoboda [Acta Cryst. (2008), E64, m246–m247]. Inclusion of the missing atom makes no significant difference to the refinement results and affects only the interpretation of the structure. A corrected scheme is shown below.

[Scheme 1]
