Dichloridodi-μ2-hydroxido-di-μ3-oxido-octaphenyltetratin(IV) dimethyl sulfoxide disolvate
Abstract
In the centrosymmetric tetranuclear title molecule, [Sn4(C6H5)8Cl2O2(OH)2]·2C2H6OS, the two independent tinIV atoms show distorted trigonal–bipyramidal SnC2O3 and SnC2O2Cl coordination geometries. The four tinIV atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn2O2 squares. The solvent molecules are linked to the tetranuclear molecule via O–H...O hydrogen bonds.
