The chromene ring system is inclined at angles of 4.78 (10) and 26.51 (10)¡ã with respect to the thiazole and benzene rings, respectively, while the thiazole ring makes a dihedral angle of 23.07 (12)¡ã with the benzene ring. The molecular structure is stabilized by an intramolecular C¡ªH...O hydrogen bond, which generates an S(6) ring motif. The crystal packing is consolidated by intermolecular N¡ªH...O hydrogen bonds, which link the molecules into chains parallel to [100], and by C¡ªH...¦Ð and ¦Ð¨C¦Ð [centroid¨Ccentroid distance = 3.4954 (15) ] stacking interactions. %U http://scripts.iucr.org/cgi-bin/paper?S1600536810018647
