Abstract
The title compound, C13H10N4O2S3, is an acylating agent which belongs to the thiazole class of organic compounds. The dihedral angle between the benzene and thiazole rings, which are fused to each other, is 1.2 (2)degrees so the overall benzothiazole system is almost planar. Intermolecular N-H center dot center dot center dot N interactions and weak C-H center dot center dot center dot O interactions between symmetry-related molecules stabilize the crystal structure, forming three different ring motifs [R-2(2)(8), R-2(2)(10) and R-2(2)(16)] in three dimensions.
