2-Hy-droxy-2-trifluoro-methyl-3,4-dihydro-2H-1-benzopyran-4-one.
The heterocyclic ring in the title compound, C(10)H(7)F(3)O(3), has a half-boat conformation with the hy-droxy-bearing C atom lying 0.595 (3) Å out of the plane of the five remaining atoms (r.m.s. deviation = 0.022 Å) in the direction of the hy-droxy O atom. Linear supra-molecular chains along the a axis, sustained by O-H⋯O hydrogen bonds between the hy-droxy H and ketone O atoms, feature in the crystal packing. These chains are connected into a three-dimensional architecture by C-H⋯O and C-H⋯F contacts.
