3,3′-Dinitro-4,4′-bipyridine

Abstract

In the title compound, C10H6N4O4, the pyridine rings are oriented at a dihedral angle of 67.8 (1)°. The O-atom pairs are trans, each displaced by a similar distance [average = 0.2331 (2) Å] out of the attached pyridine ring plane. In the crystal, intermolecular C—H...O and C—H...N interactions link the molecules into a three-dimensional network.
