The title compound, C32H18F4N4S2, is a disulfide symmetrically substituted with two diaza-meta-terphenyl groups. In the crystal, the molecule adopts a twisted conformation with a C—S—S—C torsion angle of −91.82 (7)°. One of the 4,6-(4-fluorophenyl)pyrimidine groups is virtually planar, with dihedral angles between the pyrimidine and benzene groups of 4.00 (8) and 5.44 (8)°, wheares the other is non-planar with analogues dihedral angles of 18.69 (8) and 26.60 (8)°. The planar 4,6-(4-fluorophenyl)pyrimidine groups are involved in π–π stacking interactions via their 4-fluorophenyl groups [centroid–centroid distances of 3.8556 (11) and 3.9284 (11) Å] that assemble the molecules into columns extended along the a axis. In addition, the structure is stabilized by C—F...π [F...centroid = 3.4017 (16) Å], C—H...F and C—H...π interactions.
