Abstract: In the title compound, C₁₂H₇N₃OS, the essentially planar thiazole ring (r.m.s. deviation = 0.022 Å) forms dihedral angles of 84.88 (9) and 1.8 (3)° with the phenyl ring and the -C(CN)₂ group (r.m.s. deviation = 0.003 Å), respectively. The molecule has approximate local C_s symmetry. In the crystal, molecules are linked via C-HN hydrogen bonds, forming chains propagating along [101]. The crystal studied was found to be an inversion twin with a refined 0.63 (1):0.37 (1) domain ratio.
