Bis(10-methoxybenzo[h]quinolinium) tetrachloridozinc

In the title compound, (C14H12NO)2[ZnCl4], the benzo[h]quinolinium groups are approximately planar, with maximum deviations of 0.049 (8) and 0.056 (9) . The methoxy groups are stabilized by intramolecular N—H...O hydrogen bonds. The structure also exhibits weak intermolecular N—H...Cl hydrogen bonds between the cations and anions. π–π interactions are present between the pyridinium and benzene rings [centroid–centroid distances = 3.640 (4), 3.728 (5) and 3.628 (5) ].
