Crystal structure of 4,4'-di-nitro-[1,1'-biphen-yl]-2-amine.

ABSTRACT: In the title biphenyl derivative, C₁₂H₉N₃O₄, the dihedral angle between the benzene rings is 52.84 (10)°. The nitro group attached to the benzene ring is inclined to the ring by 4.03 (2)°, while the nitro group attached to the amino-substituted benzene ring is inclined to the ring by 8.84 (2)°. In the crystal, mol-ecules are linked by two pairs of N-H⋯O hydrogen bonds, forming chains propagating along [101]. Within the chains, these N-H⋯O hydrogen bonds result in the formation of R₂²(20) and R₂²(14) ring motifs. The latter ring motif is reinforced by a pair of C-H⋯O hydrogen bonds, enclosing R₂¹(6) ring motifs. The chains are linked by a second C-H⋯O hydrogen b
