Graphical Abstract

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).

5Crystals of 1 are redissolved in water to give a concentration of about 1.5 m. Because of hydrolysis, the main mannitol species is free mannitol itself under these conditions, but about one quarter of the manitol remains in not-hydrolyzed silicate which gives rise to another set of three NMR resonance signals; signal assignment succeeds with ¹³C-enriched mannitol (in parentheses: δ_Si-bound-δ_free): C1/6 (δ=62.8, −0.5 ppm); assignment of the C2/5 (δ=75.7, 4.1 ppm) and C3/4 signals (δ=69.9, −0.4 ppm); see the interpretation of ¹³C NMR data in ref. [2b]. Note that the high Δδ of 4.1 for C2/5 is not an (unexpectedly large) CIS but clearly is caused by a significant difference between the conformations of Si-bound and free mannitol. Accordingly, DFT calculations [B3LYP/6-311+G(2d,p)//B3LYP/6-31G(d) basis set] result in Δδ values of: C1/6 3.1, C2/5 4.7, C3/4 −1.1; note that the largest deviation between calculation and experiment is to be expected for C1/6 b result of an intramolecular hydrogen bond in the calculation, which is not observed in the crystal structure. In the same calculation, an Si chemical shift of −145.0 was obtained (exp. −144.8).
