The reduction of the bulky amido-germanium(II) chloride complex, LGeCl (L = N(SiMe₃)(Ar*); Ar* = C₆H₂Me{C(H)Ph₂}₂-4,2,6), with the magnesium(I) dimer, [{(^MesNacnac)Mg}₂] (^MesNacnac = [(MesNCMe)₂CH]^{鈭?/sup>; Mes = mesityl), afforded LGeGeL, which represents the first example of a digermyne with a Ge鈥揋e single bond. Computational studies of the compound have highlighted significant electronic differences between it and multiply bonded digermynes. LGeGeL was shown to cleanly activate H₂ in solution or the solid state, at temperatures as low as 鈭?0 掳C, to give the mixed valence compound, LGeGe(H)₂L.}
