In the title compound, C33H24F2N2O2, the cyclohexane ring adopts a slightly distorted chair conformation. The dihedral angle between the planes of the phenyl rings is 71.80 (9)°, while the planes of the fluorophenyl and fluorobenzoyl rings are inclined to one another by 31.04 (10)°. The dihedral angles between the planes of the phenyl ring adjacent to the 4-hydroxy group and those of the the fluorophenyl and fluorobenzoyl rings are 51.64 (10) and 34.31 (10)°, respectively, while the corresponding angles for the phenyl ring adjacent to the 3-(4-fluorobenzoyl) group are 57.51 (9) and 85.02 (10)°, respectively. An intramolecular O—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked via pairs of O—H⋯N hydrogen bonds, forming inversion dimers. The dimers are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming chains along the c-axis direction. C—H⋯F hydrogen bonds link the chains into sheets lying parallel to the bc plane.

A mixture of (2E)-1-(4-fluorophenyl)-3-phenylprop-2-en-1-one (4.52g, 0.02 mol) and malanonitrile (0.55ml, 0.01 mol) in 30 ml ethanol in the presence of a catalytic amount of ethanoic KOH was stirred at room temperature for 6 h. The precipitate obtained was collected by filtration and purified by recrystallization from ethanol. Prismatic colourless crystals were grown from ethanol by the slow evaporation method (M.p. 497–499 K).
All of the H atoms were placed in calculated positions and refined using the riding model approximation: O-H = 0.84 Å, C-H = 0.95 - 1.00 Å with Uiso(H) = 1.5Ueq(O) and = 1.2Ueq(C) for other H atoms.

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

In order to prepare the pyran derivative, (2E)-1-(4-fluorophenyl)-3-phenylprop-2-en-1-one was reacted with malanonitrile in the presence of a catalytic amount of ethanoic KOH. Instead of the pyran derivative, the title compound was obtained and we report herein on its crystal structure. The crystal structures of related compounds have been reported (Sadikhova et al., 2011; Echeverria et al., 1995).
In the molecule of the title compound, Fig. 1, the cyclohexane ring adopts a slightly distorted chair conformation [puckering parameters Q, θ, and ϕ = 0.5873 (17) Å, 7.19 (17)° and 50.9 (13)°, respectively; Cremer & Pople, 1975]. The dihedral angle between the phenyl rings (C22-C27 and C28-C33) is 71.80 (9)° while the fluorophenyl (C14–C19) and fluorobenzoyl (C8–C13) rings are inclined to one another by 31.04 (10)°. The dihedral angle between the phenyl ring adjacent to the 4-hydroxy group [C22–C27] and the fluorophenyl and fluorobenzoyl rings is 51.64 (10) and 34.31 (10) °, respectively, while the corresponding angles for the phenyl ring adjacent to the 3-(4-fluorobenzoyl) group [C8–C13] are 57.51 (9) and 85.02 (10) °, respectively. Bond lengths are in normal ranges (Allen et al., 1987). There is an intramolecular O—H···O hydrogen bond generating an S(6) ring motif (Table 1).
In the crystal, molecules are linked via O-H···N hydrogen bonds forming inversion dimers. The dimers are linked via C-H···N and C-H···O hydrogen bonds forming chains along [001]. C-H···F hydrogen bonds link the chains to form sheets lying parallel to the bc plane (Table 1 and Fig. 2).
