MgPO4 is Low Tridymite-derived structured and crystallizes in the orthorhombic Fddd space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MgO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. Both Mg(1)-O(1) bond lengths are 1.78 Å. Both Mg(1)-O(2) bond lengths are 1.75 Å. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Mg(1)O4 tetrahedra. Both P(1)-O(1) bond lengths are 1.52 Å. Both P(1)-O(2) bond lengths are 1.53 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mg(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mg(1) and one P(1) atom. Linkers: 16 [O]P([O])([O])=O. Metal clusters: 16 [Mg]. The MOF has largest included sphere 4.77 A, density 1.51 g/cm3, surface area 2938.60 m2/g, accessible volume 0.36 cm3/g
