Comment
It is reported that benzothiazoles and their derivatives have showed a wide variety of biological activities, such as anti-inflammatory, antimycobacteriva, and capability of labeling cancer cells (Paramashivappa et al., 2002;Kočí et al., 2002;Fei et al., 2009). As an important class of benzothiazoles, benzothiazole-2-thiol also exhibits potential biological activities.
Therefore, the title compound was synthesized.
In the title compound ( Fig. 1), the dihedral angles between each benzene ring and benzothiazole ring pair where the two rings are linked to each other are 87.00and 60.18°, respectively, while the dihedral angle between the two benzene rings is 13.63°. The stability of the structure is ascribed to the weak C-H···π interactions. In the crystal (Fig. 2), the molecules are linked by weak C-H···π interactions and intermolecular S···S interactions.

Refinement
H atoms were placed in calculated positions and were refined in a riding-model approximation with C-H = 0.93 or 0.97 Å and with U iso (H) = 1.2U eq (C). Fig. 1.
