Bond lengths sulphoxide complexes

In the above manner, in dimethyl sulphoxide and dimethylformamide solutions of mercury (II) iodide-sodium iodide systems of various compositions, Gaizer and Johansson [Ga 69] determined the Hg—I bond lengths and also the I—I distances for the dissolved complexes Hgll", Hgl and Hgl2, and from these data conclusions were drawn about the symmetries of the species.
