Stannatranes and Related Systems

This section covers heterocyclic rings which contain lone pair-bearing heteroatoms within the ring so disposed as to enable additional coordination to tin, thereby generating a collection of fused, tin-containing heterocycles. These are shown in 76 and 77, bicyclic or diptych structures, and 78, a tricyclic or triptych arrangement. The term stannatrane is also commonly used in discussions of these latter systems. These compounds 

In solution, both the diptych and triptych classes of compounds are
