چکیده
The piperidin-4-one ring in the title compound, C(26)H(26)Cl(2)N(2)O, exists in a chair conformation with equatorial orientations of the methyl and 4-chlorophenyl groups. The C atom bonded to the oxime group is statistically planar (bond-angle sum = 360.0°) although the C-C=N bond angles are very different [117.83 (15) and 127.59 (15)°]. The dihedral angle between the chloro-phenyl rings is 54.75 (4)°. In the crystal, mol-ecules inter-act via van der Waals forces.

In the title compound, C(21)H(21)Cl(3)N(2)O(2), the piperidine ring adopts a distorted boat conformation. One of the chloro-phenyl rings is almost perpendicular to the best plane through piperidine ring, making a dihedral angle of 88.7 (1)°, whereas the other ring is twisted by 71.8 (1)°. The crystal packing is stabilized by inter-molecular C-H⋯O, C-H⋯Cl and O-H⋯O inter-actions.
