1-(4,5-Dinitro-10-aza-tricyclo-[6.3.1.0]dodeca-2,4,6-trien-10-yl)-2,2,2-trifluoro-ethanone.

ABSTRACT: In the title compound, C(13)H(10)F(3)N(3)O(5), a derivative of andrographolide, the five-membered ring adopts an envelope conformation, while the non-planar six-membered ring has a chair conformation. An intra-molecular C-H⋯F hydrogen bond results in the formation of a non-planar six-membered ring adopting a twisted conformation. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
