A series of oligogermanes, (Me3Si)3GeGeCl 3, (C6F5)3GeGePh3, (C6F5)3GeGe(p-Tol)3, and (C 6F5)2Ge[Ge(p-Tol)3]2, containing substituents with different electronic properties at neighboring germanium atoms were synthesized. According to X-ray diffraction studies, UV/visible spectroscopy, and quantum chemical calculations, these donor-acceptor oligogermanes are characterized by energies of electronic transitions lower than those for other similar compounds.

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.

Metallic lithium and dibenzenechromium displace thallium from (R3fGe)3HgTl*1.5DME (Rf = C6F5, DME = 1,2-dimethoxyethane) to give (R3fGe)3HgLi*3DME and fGe)4Hg>2, respectively.Reactions of thallium germylmercurate with halides of metals and organometallics in DME/EtOH solution produce ionic compounds of fGe)3Hg>-M+ type, which (depending on M ) (a) may be isolated as pure compounds, (b) disproportionate, (c) form covalent derivatives R3fGe-m or (d) undergo alcoholysis.A general scheme for the reactions has been proposed.
