The layered silicophosphate Si(HPO4)2was prepared via a novel synthesis approach using silicon nanopowder andortho‐phosphoric acid at 150 °C providing a polycrystalline product. Silicophosphate compounds with sixfold coordinated silicon atoms obtained from pyrophosphoric acid H4P2O7and tetraalkoxysilanes via a sol‐gel route exhibit the same short‐range order. The solid products were analyzed with XRD, elemental analysis (ICP‐AES), and detailed NMR spectroscopic studies, including1H,13C,29Si, and31P MAS‐,31P‐29Si‐REDOR, HETCOR, and CP‐RFDR experiments. DFT calculations support the structure of Si(HPO4)2consisting of layers of [SiO6] octahedra linked by [O3P(OH)] tetrahedra. The OH groups point to the neighboring layers and may be substituted by ethoxy or other groups.
