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?? and ?-? [centroid-centroid distance = 3.4954?(15)?Å] stacking inter-actions.

Furthermore, the crystal structure is stabilized by ?-? inter-actions between the thia-zole rings [centroid-centroid distance = 3.5476?(7)?Å].
