Description
Summary:The solid solution, sodium [iron(III)/manganese(II)] tris­(orthophosphate), Na 3.4 Mn 0.4 Fe 1.6 (PO 4 ) 3 , was obtained using a flux method. Its crystal structure is related to that of NASICON-type compounds. The [(Mn/Fe) 2 (PO 4 ) 3 ] framework is built up from an (Mn/Fe)O 6 octa­hedron (site symmetry 3.), with a mixed Mn/Fe occupancy, and a PO 4 tetra­hedron (site symmetry .2). The Na + cations are distributed over two partially occupied sites in the cavities of the framework. One Na + cation (site symmetry -3.) is surrounded by six O atoms, whereas the other Na + cation (site symmetry .2) is surrounded by eight O atoms.
