Abstract: In the imidazolium cation of the title compound, C19H19N4O2+·Cl-·C3H7NO, the dihedral angles between the imidazole ring and the phenyl rings are 85.86 (4) and 70.26 (5)°. In the crystal, N-HCl hydrogen bonds link the imdiazolium cations and chloride anions into zigzag chains along  and together with C-HCl and C-HO hydrogen bonds, which involve also the dimethylformamide solvent molecule, form a two-dimensional network extending across the ab plane.
