Abstract: In the title compound, C₃₆H₃₁ClN₂O₄Se, the four-membered [beta] -lactam ring is fused to a pyrrolidine ring. The central five-membered ring of the fused tricyclic system exhibits an envelope conformation with the N atom as the flap, while the other five-membered ring exhibits a twist conformation. The chlorophenyl ring is almost perpendicular to the pyrrolidine ring, making a dihedral angle of 73.45 (1)°. The crystal structure is stabilized by weak intermolecular C-HO interactions and the packing is further enhanced by C-H N interactions and [pi] - [pi] interactions between benzene rings of tetralone groups in molecules related by an inversion center, with a centroid-centroid separation of 3.8923 (2) Å.
