摘要：

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).
