The Crystal Structure of 2-Nitro-N-(4-nitrophenyl)benzamide

2-Nitro-N-(4-nitrophenyl)benzamide was synthesized and characterized by spectroscopy and elementalanalysis. The crystal structure was determined from single-crystal X-ray diffraction data. It crystallizesin the orthorhombic space group, P 212121, with unit cell dimensions a = 8.9443(10) ˚A, b = 9.7147(11) ˚A, and c = 13.8016(16) ˚A. The dihedral angle between the 2 aromatic rings is 82.32(4)◦. The N2 and N3 nitro groups are oriented with respect to their attached phenyl rings at dihedral angles of 1.97(3)◦ and 15.73(3)°, respectively. The intramolecular C-H. . .O hydrogen bond results in the formation of a non-planar 6-membered ring. In the crystal structure, intermolecular N-H. . .O hydrogen bonds seem to be effective in the stabilization of the structure, resulting in the formation of a 3-dimensional network.
