2,4,6-Tri­nitro­phenyl furan-2-carboxyl­ate

R. Moreno-Fuquen, F. Mosquera and A. R. Kennedy

Abstract: In the title carboxyl­ate derivative, C11H5N3O9, the picryl ring forms an angle of 75.79 (7)° with the ester fragment, indicating a near perpendicular disposition. The nitro substituents are variously oriented with respect to the picryl ring [dihedral angles = 3.22 (10), 16.03 (12) and 36.63 (10)°]. In the crystal, mol­ecules form helical chains sustained by C-H...O inter­actions along [010]. The furanyl residue is disordered, having two coplanar slightly displaced orientations [major component = 0.730 (9)].
