How does the stereochemistry of organic silicon compounds differ from their carbon analogues?

Unlike carbon atoms, which typically maintain a stable four-coordinate structure, organic silicon compounds exhibit lower energetic barriers to distortion due to their larger atomic radius. Silicon’s inability to form stable multiple bonds and lesser tendency to expand its coordination sphere beyond four-coordinate makes it more similar to its heavier congeners rather than carbon. Consequently, the study of stereochemistry in silicon compounds frequently focuses on differentiating their stereochemical behavior from that of carbon analogues.
