چکیده
In the title mol-ecule, C(18)H(12)N(6)S(2), the C-S-S-C torsion angle is 96.12 (9)°. The dihedral angles between the pyridyl and pyrimidinyl rings are 16.7 (1) and 1.27 (9)°. In the crystal, inter-molecular π-π inter-actions between the aromatic rings [centroid-centroid distances = 3.888 (2) and 3.572 (1) Å] link mol-ecules into chains propagating in [011].
