The reaction of the Grignard compound RMgBr, R = 2,4,6-iPr3C6H2, with GeCl2·(dioxane) and SnCl2 furnishes the stannagermene R2GeSnR2 (4) with a short Ge−Sn double bond length of 2.5065(5) Å. Treatment of 4 with dry oxygen at low temperature yields a 3,4-germastannadioxetane with a stretched O−O bond length.
