Abstract: In the title compound, C₄H₈NO₄⁺·C₄H₇NO₄·NO₃^-, the cation and neutral molecule are connected by an asymmetric hydrogen bond. The cation, residue 1, exists in a gauche I conformation, whereas the neutral molecule, residue 2, exhibits a gauche II conformation. A syn-syn orientation is also observed in this structure and residue 1 is involved in a straight (S1) head-to-tail sequence. The structure is stabilized by both inter- and intramolecular N-HO hydrogen bonding.
