The material described by Rb3GaO3 crystallizes in the monoclinic C2/m space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. In the third Rb site, Rb(3) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form edge-sharing GaO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Rb(1), two equivalent Rb(2), and two equivalent Ga(1) atoms. In the second O site, O(2) is bonded in a 7-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), two equivalent Rb(3), and one Ga(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
