Abstract: The piperidone ring in the title compound, C₃₁H₂₈N₂O₄, adopts the usual twist-boat conformation. The configurations of the aryl rings at the 2- and 3-positions are equatorial and those at the 5- and 6-positions are axial. The crystal structure is characterized by C-HO and C-HN hydrogen bonds between centrosymmetrically related pairs of molecules. In addition, there is an intramolecular C-HO hydrogen bond and a weak C-H interaction. No significant aryl-aryl interactions were observed.
