In the cation of the title salt, C23H27N2O4+·C2HO4-·2H2O, both fused pyrrolidine rings exhibit twisted conformations, while the piperidine rings adopt screw-boat and boat conformations. In the crystal, the three components are linked via O-HO and N-HO interactions, forming a tape along the b axis. The tapes are further linked by weak C-HO hydrogen bonds. forming a three-dimensional network.
