title: 6-Oxo-5-[(trifluoro-meth-yl)sulfon-yl]-1,2,4a,5,6,11b-hexa-hydro-1,3-dioxolo[4,5-j]phenanthridin-2-yl benzoate.
abstract: In the title compound, C(22)H(16)F(3)NO(7)S, 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 inter-molecular C-H⋯O hydrogen bonds.
