Abstract
The asymmetric unit of the title compound, [Na(C13H9BrNO4S)(H2O)(0.5)](n), contains two Na+ cations, two substituted benzoate anions and one water molecule of crystallization. The Na+ cations are coordinated in an octahedral geometry by two carboxylate O atoms, two sulfonyl O atoms and two water O atoms. The latter two ligands occupy trans positions. The polymeric network structure of the title complex is characterized by a layered assembly parallel to (001) and is further consolidated by N-H center dot center dot center dot O, O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen-bonding interactions.
