Crystal structure of 2-chloro-1-(3-methyl-2,6-diphenylpiperidin-1-yl)ethanone

Abstract

In the title compound, C20H22ClNO, the piperidine ring has a twist-boat conformation. There is an intramolecular C—H...π interaction involving the two phenyl rings which are inclined to one another by 84.91 (7)°. In the crystal, molecules are linkedviaC—H...O hydrogen bonds, forming helical chains along [010]. The chains are linked by C—H...π interactions, forming sheets parallel to (100).
