%X In the title compound, C19H11N3O2SClBr, the chromene ring system and the thiazole ring are each approximately planar, with maximum deviations of 0.033 (3)   and 0.006 (3)  , respectively. The molecule adopts an E configuration about the central C=N double bond. The central thiazole ring makes dihedral angles of 9.06 (14)¡ã and 12.07 (11)¡ã with the chloro-substituted phenyl ring and the chromene ring, respectively. The molecular structure features a short C¡ªH...O contact, which generates an S(6) ring motif. The crystal structure is stabilized by intermolecular N¡ªH...O hydrogen bonds, which link the molecules into chains along the b axis. ¦Ð¨C¦Ð stacking interactions [centroid-centroid distance = 3.4813 (15)  ] are also present.
