(5-Hy-dr-oxy-3-methyl-5-tri-fluoro-methyl-4,5-di-hydro-1H-pyrazol-1-yl)(2-hy-dr-oxy-phen-yl)methanone

摘要

In the title compound, C12H11F3N2O3, the hy-droxy-phenyl ring is twisted by 35.42?(11)° from the plane of the pyrazoline ring. The keto O atom is involved in two intra-molecular O—H?O hydrogen bonds, which generate?S(6) loops. As result, a weak intra-molecular C—H?N contact is formed, which generates an?S(7) ring motif. In the crystal, pairs of O—H?O hydrogen bonds link mol-ecules into inversion dimers with an?R22(16) motif. The dimers are linked by parallel-slipped?π–π?inter-actions [inter-centroid distance = 3.8438?(19)??], forming columns along the?c-axis direction.
