3-(4-Bromo­phenyl)-2-(3,4-di­hydro-2H-pyran-5-yl)-1,1,1-tri­fluoro­propan-2-ol

The molecular structure of the title compound, C₁₄H₁₄BrF₃O₂, adopts a bent conformation. Intramolecular O-H...F and intermolecular O-H...O interactions form a bifurcated hydrogen bond which produces a supramolecular assembly of head-to-tail dimers.

Special details

Geometry. all e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. the cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. an approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
