چکیده
In the crystal structure of the title compound, C(21)H(24)F(2)N(2)O(2), the two N atoms of the imidazolidine moiety are linked to the hy-droxy groups by intra-molecular O-H⋯N hydrogen-bonding inter-actions. The crystal studied was a racemic mixture of RR and SS enatiomers. The cyclo-hexane ring adopts a chair conformation and the imidazolidine group to which it is fused has a twisted envelope conformation.
