2,2'-(Disulfanedi-yl)bis-[4,6-(4-fluoro-phen-yl)pyrimidine].

The title compound, C(32)H(18)F(4)N(4)S(2), is a disulfide symmetric-ally substituted with two diaza-meta-terphenyl groups. In the crystal, the mol-ecule adopts a twisted conformation with a C-S-S-C torsion angle of -91.82†(7)°. One of the 4,6-(4-fluoro-phen-yl)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-fluoro-phen-yl)pyrimidine groups are involved in π-π stacking inter-actions via their 4-fluoro-phenyl groups [centroid-centroid distances of 3.8556†(11) and 3.9284†(11)†à ] that assemble the mol-ecules into columns extended along the a axis. In addition, the structure is stabilized by C-F⋯π [F⋯centroid = 3.4017†(16)†à ], C-H⋯F and C-H⋯π inter-actions.
