N,N′-Bis(pyridin-3-yl)oxamide

The title mol­ecule, C₁₂H₁₀N₄O₂, located about an inversion centre, is roughly planar, with an r.m.s. deviation from the least-squares plane of all non-H atoms of 0.019 Å. In the crystal, N—H...N hydrogen bonds between the amide N—H group and the pyridine N atom connect the mol­ecules into a corrugated layer parallel to (10-1).
