Abstract: The asymmetric unit of the title salt, C10H11N2+·C4H5O4-, consists of two independent 5-amino-6-methylquinolin-1-ium cations and two 3-carboxypropanoate anions. Both cations are protonated at the pyridine N atoms and are essentially planar, with maximum deviations of 0.026 (3) and 0.016 (2) Å. In the crystal, the cations and anions are linked via N-HO and O-HO hydrogen bonds, forming a layer parallel to the ab plane. In the layer, weak C-HO hydrogen bonds and - stacking interactions, with centroid-to-centroid distances of 3.7283 (15) and 3.8467 (15) Å, are observed. The crystal structure also features weak C-HO hydrogen bonds between the layers.
