Summary

Intamolecular Sn-N coordination controls the ring strain in the novel stannasiloxanes cyclo-R2Sn(OSiPh2)2O (4) and cyclo-(R2SnOSiPh2O)2 (5) (R = (CH2NMe2) and hence prevents their spontaneous polymerization as it is observed for related cyclo-tBu2Sn(OSiPh2)2O (1). Intramolecular Sn-N coordination also allows isolation and characterization of the first organoelement oxides cyclo-(R2SnOSiPh2OMO) (R = (CH2)3NMe2: 8, M = tBu2Ge; 9, M = PhB) with three different metals in one ring.
