Materials Data on Mg3(PO6)2 by Materials Project
Abstract
Mg3(PO6)2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded to six O atoms to form MgO6 octahedra that share a cornercorner with one MgO6 octahedra, corners with four PO4 tetrahedra, and edges with two MgO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Mg–O bond distances ranging from 1.99–2.14 Å. In the second Mg site, Mg is bonded to six O atoms to form MgO6 octahedra that share a cornercorner with one MgO6 octahedra, corners with four PO4 tetrahedra, and edges with two MgO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Mg–O bond distances ranging from 2.00–2.13 Å. In the third Mg site, Mg is bonded to six O atoms to form distorted MgO6 octahedra that share corners with two PO4 tetrahedra and an edgeedge with one PO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 1.98–2.23 Å. In the fourth Mg site, Mg is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Mg–O bond distances ranging from 1.97–2.21 Å. There are fourmore »
