Abstract : The title compound, C32H26F4N2O, crystallizes in the monoclinic space group P21/n with four mol­ecules in the unit cell. The compound was prepared by the NaBH4 reduction of 4,8,9,10-tetra­kis­(4-fluoro­phen­yl)-1,3-di­aza­adamantan-6-one in chloro­form and ethanol as solvent. The piperidine rings exhibit chair and boat conformations, and all four fluoro­phenyl groups are oriented in the equatorial direction. The crystal structure features C—H⋯F hydrogen bonds, C—H⋯π, N—H⋯π and π–π inter­actions. Hirshfeld surface and two-dimensional fingerprint analysis show that van der Waals inter­actions constitute a major contribution to the inter­molecular inter­actions, with H⋯H contacts accounting for 37.9% of the surface.
