摘要：

Anhydrous H3PO4 reacts in diethylether solution at room temperature with ethoxysilanes to form silicophosphates which contain SiO6-units. A single crystal X-ray structure provides evidence for silicophosphate structures comprised of alternating SiO4- and PO4- tetrahedra as well as SiO6-octahedra.
