Abstract
In the title molecule, C15H9N3O2S, the central imidazo[2,1-b][1,3]benzothiazole heterotricyclic unit is essentially planar (r.m.s. deviation = 0.021 Å). The terminal phenyl ring and nitro group are twisted by 9.06 (1) and 11.02 (4)°, respectively, from the mean plane of the heterotricycle. In the crystal, molecules are linked by π–π stacking interactions into columns along [100]; the interplanar distance between neighboring imidazo[2,1-b][1,3]benzothiazole planes within the columns is 3.370 (2) Å. Furthermore, the columns interact with each other by secondary S⋯O [2.9922 (10) and 3.1988 (11) Å] interactions, forming a three-dimensional framework.
