Crystal structure of RbTa(PO/sub 4/)/sub 2/ and some laws governing the structure of tantalum orthophosphates
Abstract
The authors have studied the crystal structure of RbTa(PO/sub 4/2/. An investigation of the three mixed tantalum orthophosphates TaH(PO/sub 4/)/sub 2/, and CsTa(PO/sub 4/)/sub 2/ revealed the layered structure of the crystals, and showed that, despite the identical structure of the tantalum-phosphate networks, the symmetry of the layer and the cell as a whole is influenced by the radius of the univalent cation. In the case of TaH(PO/sub 4/)/sub 2/ owing to the small size of the hydrogen atom the layers are brought so far together that in each fragment forming a layer (tantalum octahedron surrounded by six PO/sub 4/ tetrahedra) two orthophosphate tetrahedra are common to adjacent layers.
