Abstract
The title compound, C(6)H(2)F(4)N(2)O, displays amide bond lengths of 1.218 (3) Å and 1.366 (3) Å for the C=O and C-N bonds, respectively. The C(p)-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.
