Abstract: 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 CuCu separation of 6.313 (3) Å, are linked to each other, forming a chain through O-HO and O-HBr hydrogen bonds involving the half-occupied water molecule. Futhermore, weak C-HO interactions link the chains to form a supramolecular network.
