3-(4-Fluorophenyl)-1-[1′-(4-fluorophenyl)-2-oxo-5′,6′,7′,7a′-tetrahydro-1H-indole-3(2H)-spiro-3′(2′H)-1H′-pyrrolizin-2′-yl]prop-2-en-1-one

Abstract

In the title compound, C29H24F2N2O2, one of the pyrrolidine rings of the pyrrolizine system is disordered over two sites, with occupancy factors 0.734:0.266 (12). Both components of the disordered pyrrolidine ring adopt envelope conformations, whereas the other pyrrolidine ring adopts a twist conformation. The molecules are linked into centrosymmetric dimers by N—H...O hydrogen bonds and the dimers are connected via C—H...π interactions. The crystal structure is also stabilized by intermolecular C—H...F hydrogen bonds.
