Figure 1
Structural elements in Na5Fe2.5paraB and Na4Cu3paraB. (a) The [W12O40(OH)2]10− anion in Na5Fe2.5paraB connected to four Na+ and six Fe2+ ions via terminal O atoms. (b) A fragment of the infinite 1D chain in Na5Fe2.5paraB consisting of Na and Fe polyhedra. (c) The [W12O40(OH)2]10− anion in Na4Cu3paraB connected to six Na+ and six Cu2+ ions via terminal O atoms. (d) A fragment of the infinite 1D chain in Na4Cu3paraB consisting of Na and Cu polyhedra. Colour code: {WO6} are light-blue or violet octahedra, {W3O14} are blue octahedra and {W3O13} are violet octahedra, and Na atoms are green, Fe orange, Cu blue and O red. |
