The selective insertion of sulfur into the Ge-Hg bond in the ionic complex 3Hg>-Cp2CO+ results in the formation of mono-, di- and trithiolate derivatives.The compounds have been characterized by elementary analysis, IR, 19F and 199Hg NMR spectroscopy.The molecular structure of 3>--Cp2Co+ has been determined by X-ray analysis.Sulfur-containing complexes are donors of chalcogen atoms in the reactions with covalent and ionic polynuclear organometallic compounds.Ytterbium dicyclopentadienide and vanadocene displace cobaltocene from 2HgI>-Cp2Co+, and Cp2Co removes thallium from its germylmercurate complex.A general scheme for the reaction of vanadocene with cobalticinium germylmercurate has been proposed.The zerovalent triphenylphosphine complex of platinum Pt(PPh3)4 destroys the ionic structure of 2HgI>-(C6H6)2Cr+ to give dibenzenechromium iodide and a polinuclear compound with Ge-Hg-Pt-Ge chain.

The reaction of Pt(PPh3)n (n = 3 or 4) with 2Hg or (CF3)3GeHgPt(PPh3)2Ge(CF3)3 (I) gives a stable diplatinum complex 2Hg (II).X-Ray analysis has established that compound II contains a Ge-Pt-Hg-Pt-Ge chain of C2 symmetry.Both of the Pt atoms have distorted square-planar coordinations.The bond lengths are: Pt-Hg, 2.630(2) and 2.665(2) Angstroem, Ge-Pt, 2.410(4) and 2.407(4) Angstroem.Compound II reacts with dihydrogen in THF solution under mild conditions to give mercury and the hydride (CF3)3GePt(PPh3)2H.On interaction of II with R2Hg organomercurials (R = Cl, Et, GeEt3, Ge(CF3)3, Ge(C6F5)3) an unknown reaction takes place: Pt(PPh3)2 moieties migrate from the polymetallic grouping into the substrate with the formation of the corresponding RHgPt(PPh3)2R complexes or their demercuration products, R2Pt(PPh3)2 (R = Cl, Et).The latter react further with complex I formed in the first step of the process to give Hg and (CF3)3GePt(PPh3)2R.The reaction schemes are discussed.
