Zusammenfassung: 
All eight possible bicyclic molecules beta-P4SnSe3-n(I)CHI2 (n = 0-3) were formed on reaction of mixtures of the tricyclic compounds P4SnSe3-n with CHI3 in solution in CS2, and identified in the reaction mixture by analysis of their P-31 NMR spectra. Differences in coupling constants caused by the presence of sulfur rather than selenium in the products were interpreted in terms of concerted twisting of the fused five-membered rings, caused by a combination of the unsymmetric exocyclic ligand and endocyclic chalcogen substitution.
