| description |
The asymmetric unit of the title compound, 2C10H11N2
+·2C3H3O4
−·C3H4O4, consists of one 5-amino-6-methylquinolin-1-ium cation, one hydrogen malonate (2-carboxyacetate) anion and one-half molecule of malonic acid which lies on a twofold rotation axis. The quinoline ring system is essentially planar, with a maximum deviation of 0.062 (2) Å for all non-H atoms. In the anion, an intramolecular O—H⋯O hydrogen bond generates an S(6) ring. In the crystal, the components are linked via N—H⋯O and O—H⋯O hydrogen bonds into layers parallel to the ac plane. The crystal structure also features weak C—H⋯O hydrogen bonds and a π–π stacking interaction with a centroid–centroid distance of 3.8189 (10) Å. |
