Crystal structure of 1-cyclopropanecarbonyl-3-methyl-2,6-di-p-tolylpiperidin-4-one

Abstract

The title compound, C24H27NO2, crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. The two mol­ecules have very similar conformations and each exhibits an intra­molecular C—H⋯π inter­action. 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 mol­ecule A and by 68.01 (12) and 89.33 (12)° in mol­ecule B. The cyclopropanecarbonyl group is oriented at an angle of 68.5 (2)° with respect to the mean plane of the piperidine ring in mol­ecule A and 66.2 (2)° in mol­ecule B. In the crystal, the A and B mol­ecules are linked by C—H⋯O hydrogen bonds, enclosing R 2 1(6) ring motifs, forming ribbons running along the a-axis direction.
