Abstract: 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-H...O and N-H...O interactions, forming a tape along the b axis. The tapes are further linked by weak C-H...O hydrogen bonds. forming a three-dimensional network.
