In the asymmetric unit of the title salt, C14H18N2O2+·2CF3O3S−, the components are linked by two N—H
O and one C—HO hydrogen bonds. The dipyridinium salt demonstrates a skew conformation based upon C—O—C—C torsion angles of 61.5 (3) and 15.1 (4)°. A C—O—C angle of 119.3 (2)° and C—O bond distances of 1.364 (3) and 1.389 (3) Å are consistent with other dipyridyl ethers. The planes of the pyridyl rings exhibit a twist angle of 67.89 (8)°. One of the trifluoromethanesulfonate ions shows disorder of the F atoms [in a 0.52 (7):0.48 (7) occupancy ratio] and an O atom [0.64 (8):0.36 (8) occupancy ratio]. In the crystal, the components are linked by C—HO interactions, which form chains along [101].
