The material structure described by Be(PO3)2 is Low Tridymite-derived structured and crystallizes in the orthorhombic C222_1 space group. Be(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form BeO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(3)O4 tetrahedra, and corners with two equivalent P(2)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(5) atoms to form PO4 tetrahedra that share corners with two equivalent Be(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. In the second P site, P(2) is bonded to one O(1), one O(2), one O(4), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(3)O4 tetrahedra, and corners with two equivalent Be(1)O4 tetrahedra. In the third P site, P(3) is bonded to two equivalent O(3) and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with two equivalent Be(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(5) is bonded in a bent 150 degrees geometry to one Be(1) and one P(1) atom. In the second O site, O(6) is bonded in a distorted bent 120 degrees geometry to one P(2) and one P(3) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(2) is bonded in a linear geometry to one Be(1) and one P(2) atom. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one Be(1) and one P(3) atom. In the sixth O site, O(4) is bonded in a bent 150 degrees geometry to one Be(1) and one P(2) atom. is represented by the CIF file [CIF]
