(E)-3-[4-(Benzo[d]oxazol-2-yl)styryl]-1-methylpyridin-1-ium trifluoroacetate

In the title molecular salt, C21H17N2O+·CF3CO2−, the dihedral angles between the benzene ring and pendant pyridyl and benzoxazole substituents of the cation are 15.35 (10) and 2.55 (9)°, respectively. In the crystal, the components are linked by weak C—H...O hydrogen bonds, C—F...π interactions and aromatic π–π stacking interactions. The F atoms of the anion are disordered over two set of sites in a 0.536 (6):0.464 (6) ratio
