The material structure described by Rb2Be2O3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. In the second Be site, Be(2) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to three equivalent Rb(2), one Be(1), and one Be(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Rb(1), two equivalent Rb(2), one Be(1), and one Be(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
