 Title    Preparation and Crystal Structure of £7s-Tetrachlorobis(cycIooctasulfurmonoxide)tin(IV) [1]  
 Abstract    Yellow crystals of c/s-[SnCl4(S8 0) 2] containing the homocyclic sulfur oxide S80 have been prepared from the com ponents in carbon disulfide at —35 °C. A n X-ray structural analysis carried out at —105 °C showed the com pound to be monoclinic, space group P2 Jn with Z = 4 in a unit cell of dimensions a = 821.2(2) pm, b = 1331.9(4) pm , c = 2071.7(6) pm and ß -91.82(2)°. The structure was refined to a final agreem ent factor R = 0.038 for 2022 reflections. The tin atom is surrounded by a distorted octahedron of two oxygen atom s in cw-positions and four chlorine atom s in accordance with other oxygen-bonded complexes of SnCl4. The molecular symmetry is approximately C2, and the SS bond lengths in the ligands vary betw een 201 and 218 pm. V ibra­ tional spectra of [SnCl4 (SH 0) 2] are reported. The title com pound is the second example containing S80 as a ligand.
