Abstract

The mol-ecule of the title compound, C₁₇H₁₁NO₂S, is almost planar, with an inter-planar angle of 3.01 (3)° between the benzo-thia-zole and chromene ring systems. A short intra-molecular S⋯O=C contact of 2.727 (2) Å is observed. The crystal packing involves a layer structure parallel to (211), containing dimeric inversion-symmetric units connected by a 'weak' C-H⋯O=C hydrogen bond.

Keywords: benzothiazole; coumarin; crystal structure.
