In the title salt, C15H16NO4+.Br3-, classical intramolecular O-HO hydrogen bonds are found, which results in the co-planarity of the ester substituents with the quinolinium residue [C-C-C-O torsion angle = 1.0 (10)°]. The bromine anions are placed on both sides of heterocyclic cation and form BrN contacts of 3.674 (9) and 3.860 (9) Å, which confirms the location of positive charge on the N atom. Non-classical intermolecular C-HBr interactions stabilize the three-dimensional crystal structure. Moreover, anion interactions are noted [Brring centroid range = 3.367 (9)-3.697 (9) Å]. The partly saturated heterocycle is disordered over two sofa conformations with occupancies in the ratio 0.56 (2):0.44 (2).
