Green synthesis and crystal structure of 3-(benzothiazol-2-yl)thiophene

The title compound, C11H7NS2, was prepared in high yield (87%) using a solvent-free microwave-assisted synthesis. The structure shows whole-molecule disorder with occupancies for two orientations (A and B) of 0.4884 (10) and 0.5116 (10), respectively. The thiophene and benzothiazole rings are almost planar and make dihedral angles of 10.02 (18) and 12.54 (19) for orientations A and B, respectively. Slipped - stacking between the aromatic rings, together with C-H , C-H S and C-H N interactions, result in a herringbone motif in the crystal packing.
