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.

The title compound, (I) was prepared by the method of Ullmann reaction reported in literature (Kaczmarek et al. (1980). The crystals were obtained by dissolving (I) (0.2 g, 0.81 mmol) in ethanol (25 ml) and evaporating the solvent slowly at room temperature for about 5 d.
H atoms were positioned geometrically and refined as riding groups, with C—H = 0.93 Å for aromatic H, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The tittle compound, 3,3'-dinitro-4,4'-bipyridine is an important intermediate (Katritzky et al., 2006) and we report here the crystal structure of the title compound, (I).
The molecular structure of (I) is shown in Fig. 1, and the intermolecular C—H···O and C—H···N hydrogen bonds (Table 1) result in the molecular packing in three dimension (Fig. 2.). The bond lengths and angles are within normal ranges (Allen et al., 1987).
In the molecule of the title compound, the dihedral angle of the pyridine rings [(C1-C5/N1) and (C6-C10/N2)] is 67.8 (1)°.
In the crystal structure, intermolecular C—H···O and C—H···N interactions link the molecules.
