title: 3-(4-Fluoro-benzo-yl)-4-(4-fluoro-phen-yl)-4-hy-droxy-2,6-di-phenyl-cyclo-hexane-1,1-dicarbo-nitrile.
abstract: In the title compound, C33H24F2N2O2, the cyclo-hexane 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 fluoro-phenyl and fluoro-benzoyl 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 fluoro-phenyl and fluoro-benzoyl 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 intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules 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.
