S.-R. Fan, L.-G. Zhu, H.-P. Xiao and S. W. Ng

Abstract: The title complex, [Cu(C₇H₄O₆S)(C₁₀H₈N₂)(H₂O)₂]_n, consists of a polymeric neutral chain involving the 3-carboxylato-4-hydroxybenzenesulfonate ligand. The Cu atom shows a distorted octahedral coordination geometry, defined by two N atoms of the bipyridine, two O atoms of water molecules and the carboxyl O atom as well as one sulfonyl O atom of a symmetry-related bridging ligand. H atoms of water molecules are involved in O-HO hydrogen bonding, building a three dimensional network.
