Equilibrium between neutral hexacoordinate silicon complexes and ionic pentacoordinate siliconium salts through fast dissociation–recombination of the Si–Cl bond
Abstract
Equilibrium between neutral hexacoordinate silicon complexes and ionic siliconium chlorides, which is highly temperature, solvent, counterion, ligand and substituent dependent, was observed by low temperature 29Si NMR and confirmed by crystal analysis.
