Reaction of Ph6Ge2 with liquid HCl under pressure leads to di-, tri- and tetrachloro phenyldigermanes.The yield of higher chlorinated products increases with increasing pressure.The analogous reaction of Ph4Ge yields Ph2GeCl2 quantitatively.The Ge-Ge bond is most unstable in the case of Ph3Ge2Cl3 both chemically and thermally.The crystal structure of Ph2Ge2Cl4 has been determined (R = 0.057), Ge-Ge 241.3(1) pm. - Keywords: Functional Digermanes, Synthesis, Structure

Polynuclear germyl-mercury compounds are obtained from the reaction of organohydrogermanes PhnGeH4-n or digermanes Ph2nGe2H4-n (n = 1, 2) with dialkylmercury R2Hg.Di- or tri-mercurated geminal polygermates thus synthesized generally present a low stability and undergo thermal- or photodecompositions leading to the corresponding monovalent (germynes), divalent (germylenes) or, trivalent (germanium centered radicals) species and also to intermediate biradicals which could be considered as limit forms of germanium doubly-bonded compounds .Such intermediates have been chemically and spectroscopically characterized.Extension of these reactions to the silicon analogs met with difficulties, and thus previously observed differences between silicon and germanium chemistry were confirmed.
