1-(4,5-Dinitro-10-azatricyclo[6.3.1.02,7]dodeca-2,4,6-trien-10-yl)-2,2,2-trifluoroethanone

In the title compound, C13H10F3N3O5, a derivative of andrographolide, the five-membered ring adopts an envelope conformation, while the non-planar six-membered ring has a chair conformation. An intramolecular C—H⋯F hydrogen bond results in the formation of a non-planar six-membered ring adopting a twisted conformation. In the crystal structure, intermolecular C—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers.
