Oxo transfer from N2O to divalent [η4-Me8taa]Sn (Me8taaH2 = octamethyldibenzotetraaza[14]annulene) yields the oxo complex, {[η4-Me8taa]Sn(µ-O)}2; the bridging nature of the oxo ligand provides a marked contrast with the terminal sulfido and selenido counterparts, [η4-Me8taa]SnE (E = S, Se).

complexes have indicated that both the σ- and π-bonds are
polarized towards oxygen. See: J. Kapp, M. Remkc and P. v. R. Schleyer, J. Am. Chem. Soc., 1996, 118, 5745 Search PubMed; G. Trinquier, M. Pelissier, B. Saint-Roch and H. Lavayssiere, J. Organomet.
