N-(2,3,5,6-Tetrafluoropyridin-4-yl)formamide.

The title compound, C6H2F4N2O, displays amide bond lengths of 1.218 (3) Šand 1.366 (3) Šfor the C=O and C-N bonds, respectively. The Cp-N-C-O (p = pyridine) torsion angle of 179.0 (2)° indicates an anti-conformation for the grouping. Inter-molecular hydrogen bonding is observed between the amine N-H group and the carbonyl O atom, which generates chains of mol-ecules propagating along the b-axis direction.
