Crystal structure, Hirshfeld surface analysis and DFT studies of 1-[r-2,c-6-diphenyl-t-3-(propan-2-yl)piperidin-1-yl]ethan-1-one.

In the title compound, C(22)H(27)NO, the piperidine ring adopts a chair conformation. The dihedral angles between the mean plane of the piperidine ring and the phenyl rings are 89.78†(7) and 48.30†(8)°. In the crystal, mol-ecules are linked into chains along the b-axis direction by C-H⋯O hydrogen bonds. The DFT/B3LYP/6-311†G(d,p) method was used to determine the HOMO-LUMO energy levels. The mol-ecular electrostatic potential surfaces were investigated by Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter-molecular inter-actions in the mol-ecule.
