SnBr2 to yield a series of amidotetrelylenecyclophanes (:E(μ-L1)2E: and :E(μ-L2)2E:, E = Ge or Sn) and bis(halotetrelylene) complexes (:E(X)(μ-L3)(X)E:, E = Ge or Sn, X = Cl or Br; and :Ge(Cl)(μ-L4)(Cl)Ge:). Reduction of :Ge(Cl)(μ-L4)(Cl)Ge: with KC8 afforded the crystallographically characterised bis(amido/amidinatogermylene) compound, :Ge(μ-L4)2Ge:, which is believed to have formed via a disproportionation
