Project description:The asymmetric unit of the title compound, C18H16F2N2·H2O, contains two independent mol-ecules (A and B), and two independent water mol-ecules of crystallization. In mol-ecule A, the imidazole ring makes dihedral angles of 47.46?(7) and 60.98?(6)° with the 2,4-di-fluoro-phenyl and methyl-phenyl rings, respectively. The corresponding angles in mol-ecule B are 45.85?(7) and 62.78?(7)°, respectively. The dihedral angle between the two benzene rings is 64.98?(7)° in mol-ecule A and 65.53?(7)° in mol-ecule B. In the crystal, the two independent mol-ecules 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).

Project description:In the title compound, C(24)H(26)N(4)O(2), the complete mol-ecule is generated by the application of twofold symmetry. The pyrazole ring is approximately planar [r.m.s. deviation = 0.026 Å] and the benzene ring is twisted out of this plane [dihedral angle = 21.94 (7)°]. A twist in the mol-ecule about the central C-C bond [1.566 (3) Å] is also evident [C-C-C-C torsion angle = 44.30 (14)°]. Supra-molecular layers in the bc plane are formed in the crystal packing via C-H⋯O and C-H⋯π inter-actions.
