Crystal structure of 2-oxopyrrolidin-3-yl 4-(2-phenyldiazen-1-yl)benzoate

Abstract

In the title compound, C17H15N3O3, the plane of the pyrrolidone ring is inclined at an angle of 59.791 (2)° to that of the azobenzene segment, which adopts a configuration close to planar. In the crystal, molecules are oriented pairwise by (2-oxopyrrolidin-3-yl)oxy moieties at an angle of 76.257 (3)°, linked by hydrogen bonds and π-stacking interactions, forming zigzag supramolecular chains parallel to [010] further linked via additional C—H...π interactions.
