Hexacoordination of a Dimethyl Sulfide Molecule

Interaction of the trifunctional Lewis acid [(o-C₆F₄Hg)₃] (1) with dimethyl sulfide in dichloroethane leads to the formation of an extended supramolecule which features sandwiched dimethyl sulfide molecules. The sulfur atom of the latter interacts simultaneously with the mercury centers of two neighboring molecules of 1 and thereby achieves hexacoordination.
