Zusammenfassung: 
Both the fac- and mer-isomer of (i)PrSnCl3 . 2DMSO were isolated under slightly different reaction conditions. The conformations of these octahedral complexes with a cis-arrangement of the two solvent molecules were confirmed by single crystal X-ray diffraction experiments. In both cases, the asymmetric unit contains two molecules. While the fac-isomer crystallizes in the centrosymmetric space group P2(1)/n with a = 14.638(3) Angstrom, b = 15.073(3) Angstrom, c = 15.916(3) Angstrom, beta = 110.86 degrees, the mer-isomer crystallizes in the acentric space group P2(1) with a = 7.150(2) Angstrom, b = 15.155(3) Angstrom, c = 14.738(3) Angstrom, beta = 93.43(3)degrees. In both isomers the bonds trans to the isopropyl groups are shortened.
