Size matters when considering if a group 14 atom (A=silicon or carbon) can form stable, hypervalent [ClAH 3 Cl] − structures or not. In their Full Paper on page 819 ff., F. M. Bickelhaupt et al. present the ball‐in‐a‐box model that shows how silicon fits perfectly into the box formed by the substituents, whereas carbon is too small and “drops to the bottom”.
