The asymmetric unit of the title compound 2C23H27N2O4+·C8H4O42-·9H2O, contains a cation, an anionon a twofold axis and four and half molecules of water, one of which is located on the twofold axis. In the cation, both fused pyrrolidine rings exhibit twisted conformations, while the piperidine rings adopt screw-boat and boat conformations. In the crystal, the components are linked by N-HO and O-HO hydrogen bonds. The brucinium cations form typical undulating head-to-tail ribbon structuresalong the a-axis direction, which associate with the carboxy phthalate and the water molecules.
