Abstract: The molecular skeleton of the title molecule, C₂₆H₂₀N₆S₂, adopts a cis conformation with the two arms positioned on one side of the benzene ring plane. Intramolecular - interactions 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 molecular 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.
