The structure described by Rb2Be2O3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 7-coordinate geometry to one Be(1), two equivalent O(1), and four equivalent O(2) atoms. Be(1) is bonded in a distorted trigonal planar geometry to one Rb(1), 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 linear geometry to four equivalent Rb(1) and two equivalent Be(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent Rb(1) and two equivalent Be(1) atoms. is represented by the CIF card [CIF]
