Özet

The title compound, C15H12F2N2O2, crystallizes with two molecules (A and B) in the asymmetric unit. Both aromatic rings of both molecules are disordered over two orientations [occupancy ratios of 0.768 (3):0.232 (3) and 0.770 (3):0.230 (3) for molecule A and 0.789 (3):0.211 (3) and 0.789 (3):0.211 (3) for molecule B]. The dihedral angles between the planes of the major and minor components of the disordered aromatic rings are 72.0 (4) and 71.2 (4)degrees for molecule A, and 70.2 (4) and 71.5 (2)degrees for molecule B. In the crystal, both molecules form inversion dimers with R-2(2)(6) ring motifs via pairs of intermolecular O-H center dot center dot center dot N hydrogen bonds. The dimers are linked, forming zigzag C(7) chains along the c axis. Weak C-H center dot center dot center dot pi interactions help to consolidate the packing.
