1,4,8,11-Tetrakis(diiodine)-1,4,8,11-tetrathiacyclotetradecane

The title compound, C₁₀H₂₀S₄.4I₂, [14]aneS₄.4I₂, possesses crystallographically imposed inversion symmetry and has all four S donor atoms coordinated to diiodine molecules. The principal geometric parameters for the two inequivalent pairs of interactions are S—I 2.803 (2), 2.880 (2) Å, I—I 2.7894 (8), 2.7571 (10) Å and S—I—I 177.71 (5), 172.50 (4)°. Molecules of (1) are linked by S...I and I...I inter­molecular contacts to form an infinite three-dimensional lattice.
