Abstract: In the title salt, C₂H₈N⁺·C₆H₂N₃O₇^-, there is complete transfer of the OH proton from picric acid to the amine. The picrate anions lie almost parallel to the monoclinic (101) plane and are connected by OO short contacts. The ethylaminium and picrate ions are linked through N-HO and C-HO hydrogen bonds along the crystallographic b axis. In the picrate anion, tilting of the para-nitro group is a consequence of C-HO hydrogen bonding between the ions.
