title: 3-(4-Chloro-phen-yl)-4-(4-methoxyphen-yl)-6-(phenyl-selenylmeth-yl)-2,3,3a,3b,4,5,5a,6,1'',2'',3'',4''-do-deca-hydro-azeto[2',3':3,4]pyrrolo[1,2-b]isoxazole-2-spiro-2''-naphthalene-5,1''-dione.
abstract: In the title compound, C(36)H(31)ClN(2)O(4)Se, the four-membered β-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 chloro-phenyl ring is almost perpendicular to the pyrrolidine ring, making a dihedral angle of 73.45 (1)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O inter-actions and the packing is further enhanced by C-H ⋯N inter-actions and π-π inter-actions between benzene rings of tetra-lone groups in mol-ecules related by an inversion center, with a centroid-centroid separation of 3.8923 (2) Å.
