In the title compound, 2C16H15N2+·C6H4FO3S-·NO3-·0.25H2O, the two cations are nearly planar, with dihedral angles of 1.34 (14) and 4.6 (2)°, respectively, between the pyridinium and indole rings. The cations each adopt E configurations with respect to the C=C bonds and are inclined to each other with a dihedral angle of 77.66 (5)°. The ethenyl group of one cation is disordered over two sites with occupancies of 0.685 (12) and 0.315 (12), and the sulfonate group of the 4-fluorobenzenesulfonate anion is also disordered with occupancies of 0.535 (10) and 0.465 (10) for the two sets of O atoms. The anion is also inclined to the two cations, with dihedral angles between the mean planes of the benzene ring and the
-conjugated systems of the cations of 24.72 (11) and 79.83 (11)°. In the crystal structure, the cations are stacked in an antiparallel fashion into columns approximately along the a axis and are further linked through the anions into a three-dimensional network via N-H
O and C-H
O interactions. The water molecule forms O-H
O hydrogen bonds to the nitrate anion and C-H
interactions are also observed.
