Crystal structure of N-[3-(benzo[d]thia­zol-2-yl)-6-bromo-2H-chromen-2-yl­idene]-4-methyl­benzenamine

The title compound, C(23)H(15)BrN(2)OS, was the unexpected product in an attempted synthesis of the isomeric 3-(benzo[d]thia­zol-2-yl)-6-bromo-1-p-tolyl­quinolin-2(1H)-one. The C(chromene)=N—C angle is wide [125.28 (8)°]. The benzo­thia­zole and chromene ring systems are almost coplanar, with their planes parallel to (1 [Image: see text] 0); the toluene ring system is rotated by ca 40° out of the chromene plane. The mol­ecular packing involves layers with π-stacking, borderline ‘weak’ hydrogen bonds and possible C—H⋯π contacts.
