3-Phenoxy-1,4-Diphenylazetidin-2-one

Abstract

In the structure of the title compound, C<inf>21</inf>H<inf>17</inf>NO <inf>2</inf>, the fourmembered β Mactam ring is nearly planar, with long C-C distances of 1.526 (3) and 1.567 (3) A. The angles between the planes of the three phenyl rings and this group are 81.12 (8), 3.02 (8) and 49.88 (7)°. The dihedral angles between the planes of the phenyl rings are 83.72 (7), 68.03 (7) and 47.06 (6)°. The crystal structure is stabilized by inter- and intramolecular C-H⋯O hydrogen-bond interactions. © 2006 International Union of Crystallography All rights reserved.
