Crystal structure of (Z)-3-[5-chloro-2-(prop-2-yn-yloxy)phen-yl]-3-hy-droxy-1-[4-(tri-fluoro-meth-yl)phen-yl]-prop-2-en-1-one.

ABSTRACT: The title compound, C19H12ClF3O3, obtained by the photochemical transformation of 2-[5-chloro-2-(prop-2-yn-yloxy)benzo-yl]-3-[4-(tri-fluoro-meth-yl)phen-yl]oxirane adopts a Z conformation with respect to the enolic C=C double bond. The dihedral angle between the benzene rings is 12.25 (16)° and an intra-molecular O-H⋯O hydrogen bond closes an S(6) ring. An intra-molecular C-H⋯O inter-action also leads to an S(6) ring. In the crystal, very weak C-H⋯O inter-actions and short Cl⋯Cl contacts [3.3221 (16) Å] are seen, as well as weak aromatic π-π stacking inter-actions [centroid-centroid separation = 3.879 (2) Å].
