Surface| Summary: | The results has been presented of quantum-chemical calculations (DFT, B3LYP, 3‑21G) of the spatial structure and formation energy of dimers of fullerene-like spherical silicon dioxide molecules (SiO2)20(H2O)10. It has been shown that the most stable is complex with 10 hydrogen bonds between the silanol groups of the monomer molecules. Each silanol group acts as a donor of electron density and proton. The formation of covalent bonds between monomer molecules (one or five) with removal of appropriate number of water molecules is endothermic process. |
