2,6-Diformylpyridine is an organic compound with the formula C<sub>5</sub>H<sub>3</sub>N(CHO)<sub>2</sub>, and typically appears as a solid powder at room temperature. The molecule features formyl groups adjacent to the nitrogen of pyridine. The compound is prepared by oxidation of 2,6-dimethylpyridine.
It condenses with amines to give diiminopyridine ligands, as was demonstrated in Fraser Stoddart's synthesis of molecular Borromean rings. It also finds use in the preparation of metal-coordinated polymer materials.
