Crystal structure of 2-nitro-N-(2-nitro-phen-yl)benzamide.

In the title compound, C13H9N3O5, the mean plane of the non-H atoms of the central amide fragment C-N-C(=O)-C [r.m.s. deviation = 0.0442 Å] forms dihedral angles of 71.76 (6) and 24.29 (10)° with the C-bonded and N-bonded benzene rings, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds forming C(4) chains along [100]. Weak C-H⋯O contacts link the mol-ecules into (100) sheets containing edge-fused R 4 (4)(30) rings. Together, the N-H⋯O and C-H⋯O hydrogen bonds generate a three-dimensional network.
