4-(sec-butylamino)-3-nitrobenzoic acid

The asymmetric unit of title compound, C11H14N2O4, consists of two crystallographically independent molecules (A and B). In each, intramolecular N-H...O hydrogen bonds generate S(6) ring motifs. The mean plane of the nitro group forms dihedral angles of 4.5 (3) and 0.5 (3)° with the benzene ring in...
