Zusammenfassung:Building bridges: Fumed colloidal silica can be dissolved in alkaline aqueous solutions of the open‐chain sugar alcohols mannitol, xylitol, and threitol. These polyols are able to form six‐coordinate silicon complexes that are stabilized by intramolecular hydrogen bonds. The prototypical core is shown (yellow bars: the intramolecular H bonds).
