چکیده
In the title compound, C(13)H(9)F(2)N(3)O, the pyridine ring forms a dihedral angle of 16.92 (7)° with the benzene ring. In the crystal, mol-ecules are linked via N-H⋯O, C-H⋯O and C-H⋯F, with the same O atom accepting two bonds.

Nicotinohydrazide
The title mol-ecule (alternative name: pyridine-3-carbohydrazide; C(6)H(7)N(3)O) was obtained from the reaction of ethyl nicotinate with hydrazine hydrate in methanol. In the amide group, the C-N bond is relatively short, suggesting some degree of electronic delocalization in the mol-ecule. The stabilized conformation may be compared with those of isomeric compounds picolinohydrazide (pyridine-...
