diffraction analysis. Graphset analyses were performed for compounds 1 and 2. Detailed NMR spectroscopic studies including variable temperature 1H (3, 5, 6) and 119Sn (3, 4) DOSY experiments reveal the stannatrane 3 being involved in a monomer–dimer equilibrium. Both the stannatranes 3 and 4 as well as the germatranes 5 and 6 show Λ ⇌ Δ isomerization of the atrane cages in solution.
