  The first diphosphaalkenylstannylene stabilized through complexation with a carbene NHC-Sn[C(Cl)=PMes*](2) 1 (Mes* = 2,4,6-tri-tert-butylphenyl; NHC = :CN(iPr)C(Me)}(2)) was isolated and fully characterized including single crystal X-ray diffraction analysis. Its reaction with elemental sulfur rapidly gives the cyclic Sn2S2 (dithiadistannetanne) derivative 3, presumably formed by dimerization of a stannathione intermediate. By contrast, its germanium analogue NHC-Ge[C(Cl)=PMes*](2) 7 leads to the corresponding monomeric germathione 4 and germaselenone 5. The germaselenone was more stable than the germathione and could be structurally characterized. An unusual thermal cyclization reaction of the last one occurs with an excess of selenium to give the Ge2Se3 (triselenadigermolane) ring derivative 6.

  A computational study at several DFT levels of theory was performed for the mono- and diphosphaalkenyl germylene systems in order to understand the Lewis acid-base behaviour of these species towards a few electron-donor systems like tetrahydrofuran, diethyl ether and 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene or/and electron-acceptor ones, as PdCl2 and PtCl2. The ability of these species to concurrently act as a Lewis acid and base was confirmed by the experimental study (synthesis and structural characterization of a new platinum(diphosphaalkenyl) germylene) that aimed to emphasize the theoretical data obtained.
