Dichloridodi-µ(2)-hydroxido-di-µ(3)-oxido-octa-phenyl-tetra-tin(IV) dimethyl sulfoxide disolvate.

In the centrosymmetric tetra-nuclear title mol-ecule, [Sn(4)(C(6)H(5))(8)Cl(2)O(2)(OH)(2)]·2C(2)H(6)OS, the two independent tin(IV) atoms show distorted trigonal-bipyramidal SnC(2)O(3) and SnC(2)O(2)Cl coordination geometries. The four tin(IV) atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn(2)O(2) squares. The solvent mol-ecules are linked to the tetra-nuclear mol-ecule via O-H⋯O hydrogen bonds.
