R-2,c-6-Bis(4-chlorophenyl)-t-3-isopropyl-1-nitrosopiperidin-4-one

Abstract

In the title mol-ecule, C20H20Cl2N 2O2, the piperidine ring adopts a chair conformation and the nitroso group at position 1 has a bis-ectional orientation. The two benzene rings and the isopropyl group attached to the piperidine ring in positions 2, 6 and 3, respectively, have axial orientations. The dihedral angle between the two benzene rings is 21.56 (13)°. One of the Cl atoms is disordered over two positions in a 0.281 (5):0.719 (5) ratio. In the crystal structure, mol-ecules are linked by C - H⋯O hydrogen bonds and a short C - H⋯O contact occurs within the mol-ecule.
