Crystal structure of (E)-2-fluorobenzaldehyde (pyridin-2-yl)hydrazone

Abstract

The title compound, C12H10FN3, is approximately planar: the dihedral angles between the mean plane of the central N—N=C spacer unit and the fluorobenzene and pyridine rings are 14.50 (13) and 4.85 (15)°, respectively, while the dihedral angle between the aromatic rings is 16.29 (6)°. The F atom lies at the same side of the molecule as the N atom of the pyridine ring. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generateR22(8) loops. Molecules related by translation in theadirection are linked by two π–π stacking interactions involving pairs of benzene rings and pairs of pyridine rings. In each case, the ring-centroid separation is 3.8517 (9) Å. Two chains of this type pass through each unit cell, but there are no direction-specific interactions between adjacent chains.
