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

Abstract

The asymmetric unit of the title compound, C18H16F2N2·H2O, contains two independent molecules (AandB), and two independent water molecules of crystallization. In moleculeA, 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 moleculeBare 45.85 (7) and 62.78 (7)°, respectively. The dihedral angle between the two benzene rings is 64.98 (7)° in moleculeAand 65.53 (7)° in moleculeB. 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 linkedviaC—H...F hydrogen bonds, forming slab-like two-dimensional networks lying parallel to (001).
