Abstract: The structure of the title, compound C₂₃H₂₇N₂O₄⁺·C₈H₅O₄^-·3H₂O, has been determined at 130 K. The hydrogen isophthalate anions and the water molecules (one of which is disordered over two approximately equal sites) associate through extensive hydrogen-bonded interactions, including those with the common undulating brucinium cation layer substructures, forming a three-dimensional framework structure.
