چکیده
The title mol-ecule, C(18)H(12)N(4)S(3), consists of three essentially planar fragments, viz. two methyl-substituted benzonitrile rings and a substituted thia-diazole ring. The dihedral angles between the substituted benzonitrile rings and the central thia-diazole ring are 28.29 (10) and 78.83 (6)°, and the dihedral angle between the two benzonitrile rings is 72.89 (7)°.
