| Abstract: | Anhydrous H(3)PO(4) reacts in diethylether solution at room temperature with ethoxysilanes to form silicophosphates which contain SiO(6)-units. A single crystal X-ray structure provides evidence for silicophosphate structures comprised of alternating SiO(4)- and PO(4)-tetrahedra as well as SiO(6)-octahedra. |
