The cations are linked to the anions, forming ion pairs through two N-H⋯O bonds that produce characteristic R(2) (2)(8) ring motifs. These cation-anion pairs are connected through another N-H⋯O hydrogen bond, leading to an R(4) (2)(8) ring motif. Further weak C-H⋯N inter-actions link the mol-ecules along the a axis, while other C-H⋯O inter-actions generate zigzag chains extending along b.Acta crystallographica.
