title: 3-{2-[2-(2-Fluoro-benzyl-idene)hydrazin-yl]-1,3-thia-zol-4-yl}-2H-chromen-2-one.
abstract: In the title compound, C(19)H(12)FN(3)O(2)S, the chromene ring system and the thia-zole ring are approximately planar [maximum deviations of 0.023 (3) Å and 0.004 (2) Å, respectively]. The chromene ring system is inclined at angles of 4.78 (10) and 26.51 (10)° with respect to the thia-zole and benzene rings, respectively, while the thia-zole ring makes a dihedral angle of 23.07 (12)° with the benzene ring. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. The crystal packing is consolidated by inter-molecular N-H⋯O hydrogen bonds, which link the mol-ecules into chains parallel to [100], and by C-H⋯π and π-π [centroid-centroid distance = 3.4954 (15) Å] stacking inter-actions.
