The present review provides a comprehensive survey on the molecular st
ructure of sila-heterocyclic compounds (silacyclopropanes, silacyclobu
tanes, silacyclopentanes, silacyclohexanes and derivatives with larger
rings, as well as compounds with fused and unsaturated heterocycles).
In a lot of cases the heterocycles include also heteroatoms other tha
n silicon, however, all silaheterocycles under consideration contain o
nly Si-C bonds.
