Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C33H26N2O2, the pyrrolidine ring adopts an envelope conformation with the N atom deviating by 0.600 (1) angstrom from the plane of the other four atoms. The molecule is stabilized by weak intramolecular C-H...O interactions and the crystal packing is stabilized by N-H...O and C-H...O hydrogen bonds, generating centrosymmetric dimers of R-2(2)(10) and R-2(2)(14) rings.
