Structure
The structure of diorganotin oxides depends on the size of the organic groups.
For smaller substituents, the materials are assumed to be polymeric with five-coordinate Sn centers and 3-coordinate oxide centers.
The result is a net of interconnected four-membered Sn2O2 and eight-membered Sn4O4 rings.
The presence of pentacoordinate Sn centers is deduced from 119Sn NMR spectroscopy and 119Sn Mössbauer spectroscopy.
