title: Poly[[hexaaquabis[mu4-2-hydroxy-5-(4-sulfonatophenyldiazenyl)benzoato]dibarium(II)] 4,4'-bipyridine solvate].
abstract: The title compound, {[Ba2(C(13)H(8)N(2)O(6)S)2(H2O)6].C(10)H(8)N(2)}n, possesses a novel two-dimensional porous coordination network, in which each Ba(II) ion is nine-coordinated by three carboxylate O atoms, two sulfonate O atoms and four water molecules in an irregular coordination environment. Hydrogen-bond interactions between coordinated water molecules and sulfonate/hydroxyl groups hold the network layers together and produce a three-dimensional supramolecular architecture.
