6-Oxo-5-[(trifluoromethyl)sulfonyl]-1,2,4a,5,6,11b-hexahydro-1,3-dioxolo[4,5-j]phenanthridin-2-yl benzoate

Abstract

In the title compound, C22H16F3NO7S, the two benzene rings are almost perpendicular, the dihedral angle between their mean planes being 87.1 (1)°. The terminal O atom of the benzoate moiety is disordered over two positions with site occupancies of 0.244 (15) and 0.756 (15). The crystal structure is stablized by two types of weak intermolecular C—H...O hydrogen bonds.
