title: (E)-6-Bromo-3-{2-[2-(4-chloro-benzyl-idene)hydrazin-yl]thia-zol-5-yl}-2H-chromen-2-one.
abstract: In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and the chromene ring, respectively. The mol-ecular structure features a short C-H⋯O contact, which generates an S(6) ring motif. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, which link the mol-ecules into chains along the b axis. π-π stacking inter-actions [centroid-centroid distance = 3.4813 (15) Å] are also present.
