From conversions of Ar2SnH2(Ar = Tripp, Dipp; Tripp = 2,4,6-Triisopropylphenyl, Dipp = 2,6-Diisopropylphenyl), and a bismuth(iii) amide, Bi[N(SiMe3)2]3, we isolated the first representatives of mixed, uncharged Bi/Sn clusters, Bi8Sn3Ar6. Along with unprecedented bicyclo[2.2.0]hexanes, (HAr2Sn)2Sn2Bi4, these have been characterized by single crystal X-Ray diffraction, heteronuclear NMR, vibrational and UV-Vis spectroscopy. Quantum-chemical calculations were carried out in order to understand bonding within the isolated polyhedral compounds.

A study was conducted on a molecule with a Ge=Sn double bond. The treatment of R2Ge=SnR2 with dry oxygen yielded a 3,4-germastannadioxetane with a stretched O-O bond length. It was found that the four-membered heterocyclic ring was folded from the torsion angle Ge-O-O-Sn of 31.4°.

The species iPr3-2,4,6)2>3> has been obtained in a simple, essentially quantitative, synthesis from SnCl2 and ArLi in diethyl ether at low temperature.The crystal structure analysis confirms the trimeric nature of the molecular units but reveals some unusual features.The crystal contains the unusual feature of an asymmetric unit that consists of three units of 3> in P21/c; the molecular unit is a scalene triangle, showing high consistency between the three molecules, in contrast to analogous trimeric species of silicon or germanium.The Sn-Sn bonds are lengthened (average value 2.942 Angstroem) owing to steric crowding.
