cis-1,2-Bis{[4-(4-pyrid­yl)pyrimidin-2-yl]sulfanylmeth­yl}benzene

The mol­ecular skeleton of the title mol­ecule, 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. Intra­molecular π–π 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.
