2-Methyl-amino-5-nitro-benzoic acid.

ABSTRACT: The title compound, C(8)H(8)N(2)O(4), is almost planar (r.m.s. deviation = 0.037?Å) and an intra-molecular N-H?O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H?O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H?O hydrogen bonds (involving the same H atom that forms the intra-molecular hydrogen bond) link the dimers into infinite sheets lying parallel to (102).

The title compound, C(8)H(8)N(2)O(4), is almost planar (r.m.s. deviation = 0.037 Å) and an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H⋯O hydrogen bonds (involving the same H atom that forms the intra-molecular hydrogen bond) link the dimers into infinite sheets lying parallel to (102). ...[more]
