A new germanium(II) phosphate, sodium tetragermanium tris(phosphate), Na[Ge 4 (PO 4) 3], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn 4 (PO 4) 3](A = Na, K, NH 4). It features a [Ge 4 (PO 4) 3] framework made up of GeO 3 pyramids and PO 4 tetrahedra, which are linked by shared corners, yielding a three ...
There is a three step approach to determining the geometry of a molecule. Determine the Lewis dot structure of the compound. Determine the Electron geometry from the Lewis dot structure. Determine the molecular geometry. It is very important from the onset that students understand the difference between electronic geometry and molecular geometry.
1 sty 2023 · Considering P–O bonds in amorphous P 2 O 5, the structure of phosphate glasses was analyzed. Results revealed that the basic structural element of phosphate glasses is the (PO 4) tetrahedron.
