2-(2,4-Difluorophenyl)-4,5-dimethyl-1-(4-methylphenyl)-1 H -imidazole monohydrate

The asymmetric unit of the title compound, C 18 H 16 F 2 N 2 ·H 2 O, contains two independent molecules ( A and B ), and two independent water molecules of crystallization. In molecule A , the imidazole ring makes dihedral angles of 47.46 (7) and 60.98 (6)° with the 2,4-difluorophenyl and methylphenyl rings, respectively. The corresponding angles in molecule B are 45.85 (7) and 62.78 (7)°, respectively. The dihedral angle between the two benzene rings is 64.98 (7)° in molecule A and 65.53 (7)° in molecule B . In the crystal, the two independent molecules are linked by O—H...N and O—H...O hydrogen bonds, forming chains propagating along [100]. These chains are linked via C—H...F hydrogen bonds, forming slab-like two-dimensional networks lying parallel to (001).
