Crystal structure of 2-methyl-3-nitrobenzoic anhydride

Abstract

The title molecule, C16H12N2O7, lies on a twofold rotation axis which bisects the central O atom. The dihedral angle between two symmetry-related benzene rings is 48.54 (9)°. In the crystal, molecules are linked by weak C—H...O hydrogen bonds which generate C(13) chains running parallel to [31-1].
