N2  - Efficient syntheses of the cis and trans isomers of &#91;OsCl2(Me2SO)4&#93; are reported. While a structural study of thetrans isomer confirms the spectroscopically assigned all-S-bound Me2SO configuration, a crystallographic determination of the cis isomer reveals a previously unheralded all-S-bound Me2SO geometry, in contrast to the spectroscopically inferred configuration predominant in solution which has one O-bound ligand. Fortrans-&#91;OsCl2(Me2SO)4&#93;, crystals are tetragonal, space group I 4/m, with a 9&#183;092(2), c 11&#183;212(3) &#197;, Z 2, 566 unique reflections (34 parameters), converging at R 0&#183;026 and Rw 0&#183;032. For cis-&#91;OsCl2(Me2SO)4&#93;, crystals are triclinic, space group P-1, with a 8&#183;193(2), b 8&#183;941(3), c 13&#183;837(3) &#197;, &#945; 79&#183;77(2), &#946; 79&#183;91(2), &#947; 65&#183;03(2)&#176;, Z 2, 4152 unique reflections (173 parameters), converging at R 0&#183;021 and Rw 0&#183;018.
