The compound described by Mg(Sb2O5)2 crystallizes in the orthorhombic Amm2 space group. Mg(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(4), and four equivalent O(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 20-47°. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1), one Sb(1), and one Sb(2) atom to form a mixture of edge and corner-sharing OMg2Sb2 tetrahedra. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Sb(2) and two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Mg(1), one Sb(1), and two equivalent Sb(2) atoms. In the fifth O site, O(5) is bonded in a water-like geometry to one Sb(1) and one Sb(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to two equivalent Sb(2) atoms. is represented by the CIF file [CIF]
