(E)-1,3-Dimethyl-2,6-di-phenyl-piperidin-4-one O-(phen-oxy-carbon-yl)oxime.

ABSTRACT: The title piperidine derivative, C26H26N2O3, has an E conformation about the N=C bond. The piperidine ring has a chair conformation and its mean plane is almost perpendicular to the attached phenyl rings, making dihedral angles of 87.47?(9) and 87.34?(8)°. The planes of these two phenyl rings are inclined to one another by 60.38?(9)°. The plane of the terminal phenyl ring is tilted at an angle of 32.79?(9)° to the mean plane of the piperidine ring. The mol-ecular conformation is stabilized by two intra-molecular C-H?O contacts. There are no significant inter-molecular inter-actions in the crystal.
