(5-Hydroxy-3-methyl-5-trifluoromethyl-4,5-dihydro-1H-pyrazol-1-yl)(2-hydroxyphenyl)methanone

In the title compound, C12H11F3N2O3, the hydroxyphenyl ring is twisted by 35.42 (11)° from the plane of the pyrazoline ring. The keto O atom is involved in two intramolecular O—H...O hydrogen bonds, which generate S(6) loops. As result, a weak intramolecular C—H...N contact is formed, which generate...

Description
Summary:In the title compound, C12H11F3N2O3, the hydroxyphenyl ring is twisted by 35.42 (11)° from the plane of the pyrazoline ring. The keto O atom is involved in two intramolecular O—H...O hydrogen bonds, which generate S(6) loops. As result, a weak intramolecular C—H...N contact is formed, which generates an S(7) ring motif. In the crystal, pairs of O—H...O hydrogen bonds link molecules into inversion dimers with an R22(16) motif. The dimers are linked by parallel-slipped π–π interactions [intercentroid distance = 3.8438 (19) Å], forming columns along the c-axis direction.
