Article abstract of DOI:10.1107/S0108270198011731

The title compound, C₁₁H₈N₂S, already known from the literature, was prepared and studied by X-ray diffraction. The five-membered heterocyclic ring is coplanar with its fused benzene ring. However, the molecule itself is non-planar, with the dihedral angle between the planes of the 2-benzothiazolyl and pyrrolyl groups being 17.3 (7)°. The molecules related by the twofold rotation axis are connected in pairs by N - H...N hydrogen bonds of 3.032 (9) A.
