Abstract: In the title compound, [Cu(C₇H₃NO₇S)(C₁₀H₈N₂)(H₂O)]·0.5C₁₀H₈N₂, the Cu^II atom is six-coordinated by two N atoms from two different bipyridine (bipy) ligands, one sulfonate O atom and two carboxylate O atoms from three 2-nitro-5-sulfonatobenzoate ligands and one water O atom in a distorted octahedral geometry. The bipy solvent molecule lies on an inversion center. The Cu^II atoms are linked by the bipy ligands, forming one-dimensional chains, which are connected by the 2-nitro-5-sulfonatobenzoate ligands into a two-dimensional layer-like network. The two-dimensional structure is extended by O-HO and O-HN hydrogen bonds into a three-dimensional supramolecular network.
