Ethylaminium picrate

In the title salt, C2H8N+center dot 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 O center dot center dot center dot O short contacts. The ethylaminium and picrate ions are linked through N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds along the crystallographic b axis. In the picrate anion, tilting of the para-nitro group is a consequence of C-H center dot center dot center dot O hydrogen bonding between the ions.
