title: 1-{(Z)-1-(2,4-Dichloro-phen-yl)-1-[2-(4-methyl-phen-oxy)eth-oxy]prop-1-en-2-yl}-1H-imidazol-3-ium nitrate.
abstract: In the title salt, C21H21Cl2N2O2(+)·NO3(-), the imidazole ring makes dihedral angles of 43.39 (14) and 10.9 (2)° with the 4-methyl-phenyl and 2,4-dichloro-phenyl rings, respectively. The mol-ecule adopts a Z conformation about the C=C double bond, which links the imidazole ring to the 4-methyl-phen-oxy unit via an eth-oxy chain. In the crystal, cations and anions are linked into chains by N-H⋯O and C-H⋯O hydrogen bonds.
