Abstract

In the title compound, C20H16F2O2, the cyclo­hex-2-en-1-one ring adopts a distorted envelope conformation and the dihedral angles between its six-atom mean plane and the fluorophenyl rings are 38.9(8) and 82.3(1)°. The two fluoro­phenyl rings are oriented at an angle of 77.3 (3)°. The long hy­droxy O—H bond length of 1.22 (3) and the H⋯O distance of 1.28 (3) Å, together with a longer than expected C=O bond length [1.290 (2) Å] in the hy­droxy(en-1-one) group, indicate sharing of the H atom as O⋯H⋯O between the two O atoms and the influence of electron delocalization. Weak C—H⋯O inter­molecular inter­actions form an infinite two-dimensional network in (011).
