Pentathia- and pentaselena-distannabicyclo[3.1.1]heptanes reacted with tributylphosphine to afford tetrathia- and tetraselena- distannabicyclo[2.1.1]hexanes, respectively. The novel heterocyclic framework of a tetrathiadistannabicyclo[2.1.1]hexane was demonstrated by X-ray structural analysis. Structures of a series of pentachalcogena and tetrachalcogena derivatives are discussed.
