Reduction of Ge(Cl)C6H3mes2-2,6 to give the cyclotrigermenyl radical (GeC6H3mes2-2,6)3· and the trigermenyl anion salt K(GeC6H3mes2-2,6)3

Treatment of Ge(Cl)C 6 H 3 mes 2 -2,6 1 with 1 equiv. of KC 8 furnishes the new cyclotrigermenyl radical (GeC 6 H 3 mes 2 -2,6) 3 ·, 2) which is characterized by EPR and X-ray crystallography; reduction with a further equivalent of KC 8 gives the new trigermenyl allyl anion analogue K(GeC 6 H 3 mes 2 -2,6) 3 which has an open Ge 3 framework with a wide Ge–Ge–Ge angle of 159.19(10)°at the central Ge and a Ge–Ge distance of 2.422(2) Å.
