✦ Synopsis

In the molecule of the title compound, C 16 H 9 NO 3 S, the two fused ring systems are each planar and make a dihedral angle of 78.0 (1) with each other. In the crystal structure, intermolecular C-HÁ Á ÁO hydrogen bonds link the molecules into chains along the b axis and there are alsostacking interactions. The distance between the adjacent ring centroids of the benzoxazole system is 3.89 (1) A ˚(symmetry code linking the adjacent rings: 1 À x, 1 À y, 1 À z). A further interaction occurs between two adjacent six-membered benzoxazole benzene rings (symmetry code: 1 À x, Ày, 1 À z), with a centroid -to-centroid distance of 3.93 (1) A ˚.
