First impressions : An oxidative addition between [LGeOH] and elemental sulfur leads to the isolation of the first germacarboxylic acid [LGe(S)OH] (L=HC{(CMe)(2,6‐ i Pr 2 C 6 H 3 N)} 2 ; see picture). In the solid state [LGe(S)OH] displays preferential of the thiono‐form and formation of hydrogen‐bond arrays generates dimers. This germacarboxylic acid shows how the heavier congeners of Group 14 can mimic well know organic functional groups.
