1,2,4,5-Tetra-fluoro-3,6-diiodo-benzene-4-(pyridin-4-ylsulfan-yl)pyridine (1/1).


ABSTRACT: The asymmetric unit of the title 1:1 adduct, C(10)H(8)N(2)S·C(6)F(4)I(2), comprises a half-mol-ecule of 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene, and half a 4-(pyridin-4-ylsulfan-yl)pyridine mol-ecule. The former is completed by crystallographic inversion symmetry, the latter by twofold symmetry, with the S atom lying on the rotation axis. The almost planar 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene mol-ecule (r.m.s. deviation of all 12 atoms = 0.016?Å) and twisted 4-(pyridin-4-ylsulfan-yl)pyridine mol-ecule [dihedral angle between pyridyl rings = 54.88?(13)°] are connected by N?I inter-actions [2.838?(4)?Å], generating a supra-molecular chain with a step-ladder topology. These chains are connected in the crystal by C-H?F and C-H??(pyrid-yl) inter-actions.
