In the title molecule, C9H6BrNS, the planes of the 2-bromo-1,3-thiazole and phenyl rings are inclined at 7.45 (10)° with respect to each other. In the crystal, molecules related by a centre of symmetry are held together via π–π interactions, with a short distance of 3.815 (2) Å between the centroids of the five- and six-membered rings. The crystal packing exhibits short intermolecular SBr contacts of 3.5402 (6) Å.

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 SO [2.9922 (10) and 3.1988 (11) Å] interactions, forming a three-dimensional framework.

In the title molecule, C16H15BrN2S2, the central imidazo[2,1-b]thiazole fragment is almost planar (r.m.s. deviation = 0.012 Å), and the fused 5,6,7,8-tetrahydrobenzene ring adopts an unsymmetrical half-chair conformation. The dihedral angle between the imidazo[2,1-b]thiazole and benzene planes is 18.25 (4)°. The terminal methylsulfanyl substituent lies practically within the benzene plane [the dihedral angle between the corresponding planes is 7.20 (10)°] and is turned toward the C—Br bond. In the crystal, molecules form infinite chains along [100] via secondary BrN interactions [3.1861 (16) Å]. The chains are arranged at van der Waals distances.
