| Figure 2 The [(Fe/Al)3(PO4)3(OH)2] layers are stacked along [010]. They are connected by H2O and cations Ca2+ and Mg2+. Yellow and green octahedra represent (Fe/Al)O6 and MgO6 groups, respectively. Purple tetrahedra represent PO4 groups. Grey, aquamarine, blue and red spheres represent Ca2+ cations, H2O molecules, H atoms and O atoms, respectively. |
