The compound described by RbBePO4 crystallizes in the orthorhombic Pna2_1 space group. Rb(1) is bonded in a 11-coordinate geometry to two equivalent O(4), three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Be(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form BeO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with four equivalent Be(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to three equivalent Rb(1), one Be(1), and one P(1) atom. In the second O site, O(2) is bonded in a linear geometry to three equivalent Rb(1), one Be(1), and one P(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to three equivalent Rb(1), one Be(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Rb(1), one Be(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
