N′-[(1E)-1-(2-Fluorophenyl)ethylidene]pyridine-3-carbohydrazide
The title compound, C(14)H(12)FN(3)O, adopts an E conformation with respect to the azomethine double bond whereas the N and methyl C atoms are in a Z conformation with respect to the same bond. The ketonic O and azomethine N atoms are cis to each other. The non-planar molecule [the dihedral angle b...

Sumario: | The title compound, C(14)H(12)FN(3)O, adopts an E conformation with respect to the azomethine double bond whereas the N and methyl C atoms are in a Z conformation with respect to the same bond. The ketonic O and azomethine N atoms are cis to each other. The non-planar molecule [the dihedral angle between the benzene rings is 7.44 (11)°] exists in an amido form with a C=O bond length of 1.221 (2) Å. In the crystal, a bifurcated N—H⋯(O,N) hydrogen bond is formed between the amide H atom and the keto O and imine N atoms of an adjacent molecule, leading to the formation of chains propagating along the b-axis direction. Through a 180° rotation of the fluorophenyl ring, the F atom is disordered over two sites with an occupancy ratio of 0.632 (4):0.368 (4). |
