Abstract
In the title compound, C17H10Cl2N4OS, the phenyl ring and the H atoms attached to the adjacent C atom are disordered over two positions, with refined site occupancies of 0.509 (8) and 0.491 (8). The planar 4H-1,3,4-thiadiazolo[2,3-c][1,2,4]triazine ring system [maximum deviation = 0.048 (3) Å] forms dihedral angles of 76.9 (5), 74.9 (5) and 9.88 (12)°, respectively, with the major and minor parts of the disordered phenyl ring and with the dichloro-substituted benzene ring. In the crystal, pairs of C—H⋯O hydrogen bonds link the molecules, forming inversion dimers with an R 2 2(18) graph-set motif. A short S⋯N contact of 2.801 (3) Å is observed between the dimers.
