1-[(Z)-8-(4-Chlorophenoxy)-3-(2,4-difluorophenyl)-4-oxaocta-2-en-2-yl]-1H-1,2,4-triazol-4-ium nitrate

In the title compound C21H21ClF2N3O2+·NO3−, the triazole ring makes dihedral angles of 40.7 (3) and 30.2 (4)° with the 4-chloropheny and 2,4-difluorophenyl rings, respectively. The cation adopts a Z-configuration about the C=C double bond which links the triazole ring to the 4-chlorophenoxy unit via a butyloxy chain. In the crystal, the cations and the anions are linked by N—H...O, C—H...O and C—H...F hydrogen bonding.
