The material structure described by CsMgPO4 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. Mg(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form MgO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Mg(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mg(1) and one P(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Cs(1), one Mg(1), and one P(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Mg(1) and one P(1) atom. is represented by the CIF card [CIF]
