Beschreibungen/Notizen

• The unit cell of NaNiAsO 4 is rhombohedral, space group R 3, with a = 4.955(5) Å, c = 26.47(3) Å and Z - 6. The crystal structure com­prises three-layer units consisting of one “octahe­dral" layer, built up from Ni0 6 -octahedra, and two “tetrahedral" layers, built up from AsO 4 -tetrahe- dra. Sodium ions are situated between these layers, having a distorted (4+3) coordination.
