title: Crystal structure of 1-cyclo-propane-carbon-yl-3-methyl-2,6-di-p-tolyl-piperidin-4-one.
abstract: The title compound, C24H27NO2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules have very similar conformations and each exhibits an intra-molecular C-H⋯π inter-action. The central piperidine rings adopt boat conformations and the p-tolyl rings are inclined to the mean plane of the piperidine ring by 71.21 (11) and 89.86 (12)° in mol-ecule A and by 68.01 (12) and 89.33 (12)° in mol-ecule B. The cyclopropanecarbonyl group is oriented at an angle of 68.5 (2)° with respect to the mean plane of the piperidine ring in mol-ecule A and 66.2 (2)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked by C-H⋯O hydrogen bonds, enclosing R 2 (1)(6) ring motifs, forming ribbons running along the a-axis direction.
