Abstract

The title salt, C 3 H 5 N 2 + C 10 H 6 NO 4 - , was obtained during a study of the co-crystallization of N′-[bis(1H-imidazol-1-yl)methylene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å] . In the crystal, cations and anions are linked via classical N - O hydrogen bonds and weak C - O hydrogen bonds, forming a three-dimensional network. Weak C - π interactions and π-π stacking interactions [centroid-centroid distances = 3.4728 (13) and 3.7339 (13) Å] also occur in the crystal.
