Bottom Line: The title compound, C(12)H(6)N(4)O(8), is a biphenyl system that was synthesized as a building block for a new series of anti-malarial compounds.Furthermore, the three ring C atoms around the ring-ring linkage belong to a plane inclined by 4.5 (1)° in relation to the plane containing the other three C atoms, i.e. (NO(2)-)C-C-C(NO(2)).This distortion of the ring causes uncommonly short intermolecular O⋯O [3.038 (2) Å] and O⋯C [3.000 (4) and 3.214 (1) Å] contacts.

ABSTRACT
The title compound, C(12)H(6)N(4)O(8), is a biphenyl system that was synthesized as a building block for a new series of anti-malarial compounds. The aromatic rings are oriented at a dihedral angle of 45.5 (2)°, and inter-molecular short O⋯O contacts form a chain along the b axis. The strength of the inter-actions involved in this chain cause one of the rings to be slightly distorted, with the torsion angle between the nitro groups being 23.4 (2)°, whereas, in the other ring, both nitro systems are parallel, forming an angle of 9.6 (2)° with the plane of the aromatic ring to which they are bound. Furthermore, the three ring C atoms around the ring-ring linkage belong to a plane inclined by 4.5 (1)° in relation to the plane containing the other three C atoms, i.e. (NO(2)-)C-C-C(NO(2)). This distortion of the ring causes uncommonly short intermolecular O⋯O [3.038 (2) Å] and O⋯C [3.000 (4) and 3.214 (1) Å] contacts.
