The title complex, [Cu3(C9H8BrNO4S)2(C7H4BrO2)2(C10H8N2)2]·H2O, lies on an inversion center located on the central Cu atom, which is four-coordinated in a square-planar geometry, whereas the outer Cu atoms related by symmetry are five-coordinated in a square-pyramidal geometry. The trinuclear molecules, with an intramolecular Cu⋯Cu separation of 6.313 (3) Å, are linked to each other, forming a chain through O—H⋯O and O—H⋯Br hydrogen bonds involving the half-occupied water molecule. Futhermore, weak C—H⋯O interactions link the chains to form a supramolecular network.
