Crystal structure of 3-(benzo[d]thiazol-2-yl)-6-methyl-2H-chromen-2-one

Abstract

The molecule of the title compound, C17H11NO2S, is almost planar, with an interplanar angle of 3.01 (3)° between the benzothiazole and chromene ring systems. A short intramolecular 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.
