The crystal structure described by Mg(Sb2O5)2 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form MgO6 octahedra that share corners with four equivalent Sb(1)O4 tetrahedra and edges with four equivalent Sb(2)O6 octahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form SbO4 tetrahedra that share corners with two equivalent Mg(1)O6 octahedra and corners with four equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-61°. In the second Sb site, Sb(2) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with four equivalent Sb(1)O4 tetrahedra,  an edgeedge with one Sb(2)O6 octahedra, and edges with two equivalent Mg(1)O6 octahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1) and two equivalent Sb(2) atoms. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
