Crystal structure of 2-methyl-3-nitro-benzoic anhydride.
The title mol-ecule, C16H12N2O7, lies on a twofold rotation axis which bis-ects the central O atom. The dihedral angle between two symmetry-related benzene rings is 48.54 (9)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds which generate C(13) chains running parallel to [31-1].
