The material described by RbBe2P3O10 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. Be(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form BeO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra and corners with three equivalent P(1)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra and corners with three equivalent Be(1)O4 tetrahedra. In the second P site, P(2) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with two equivalent Be(1)O4 tetrahedra and corners with two equivalent P(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Rb(1), one Be(1), and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Rb(1), one Be(1), and one P(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Rb(1), one P(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one Be(1), and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Be(1), and one P(1) atom. is represented by the CIF file [CIF]
