The mol-ecular skeleton of the title mol-ecule, C(26)H(20)N(6)S(2), adopts a cis conformation with the two arms positioned on one side of the benzene ring plane. Intra-molecular π-π inter-actions between the pyrimidine rings [centroid-centroid distance = 3.654 (2) Å] and between the pyridine rings [centroid-centroid distance = 3.775 (2) Å] help to set the mol-ecular conformation; the pyrimidine rings, as well as the pyridine rings, are nearly parallel, forming dihedral angles of 4.12 (14) and 2.46 (14)°, respectively.
