Abstract

The title compound, [Cd(C14H8O6S)(H2O)2]n, comprises zigzag chains parallel to [111] of alternating [Cd(H2O)2]2+ and sulfonyl­dibenzoate units, with the Cd and S atoms lying on crystallographic twofold axes. The central CdII ion is in a slightly distorted octa­hedral geometry, coordinated by six O atoms from two carboxyl­ate groups and two water O atoms. An intra­molecular C—H⋯O hydrogen bond occurs. In the crystal, inter­molecular hydrogen bonds between carboxyl­ate O atoms and coordinated water mol­ecules in adjacent chains lead to the formation of a three-dimensional network structure. The compound is isotypic with the Zn analog.
