Rb2MgO2 crystallizes in the orthorhombic Pbcn space group. Rb(1) is bonded in a 5-coordinate geometry to five equivalent O(1) atoms. Mg(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing MgO4 tetrahedra. O(1) is bonded in a 2-coordinate geometry to five equivalent Rb(1) and two equivalent Mg(1) atoms.
Rb2MgO2 crystallizes in the orthorhombic Pbcn space group. Rb(1) is bonded in a 5-coordinate geometry to five equivalent O(1) atoms.
