3-(Benzo[ d ]thia-zol-2-yl)-2 H -chromen-2-one.

In the title compound, C 16 H 9 NO 2 S, the inter-planar angle is 6.47 (6)°. An intra-molecular S⋯O=C contact of 2.727 (2) Å is observed. The packing is determined by several types of weak inter-action ('weak' hydrogen bonds, S⋯S contacts and π-π stacking).
