Rb2Li3GaO4 crystallizes in the orthorhombic Ibam space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent O(1) atoms to form distorted LiO4 tetrahedra that share corners with two equivalent Li(2)O4 tetrahedra, corners with two equivalent Ga(1)O4 tetrahedra,  an edgeedge with one Li(2)O4 tetrahedra,  an edgeedge with one Ga(1)O4 tetrahedra, and edges with two equivalent Li(1)O4 tetrahedra. In the second Li site, Li(2) is bonded to four equivalent O(1) atoms to form distorted LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, edges with two equivalent Li(1)O4 tetrahedra, and edges with two equivalent Ga(1)O4 tetrahedra. Ga(1) is bonded to four equivalent O(1) atoms to form distorted GaO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, edges with two equivalent Li(1)O4 tetrahedra, and edges with two equivalent Li(2)O4 tetrahedra. O(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1), one Li(2), two equivalent Li(1), and one Ga(1) atom.
Rb2Li3GaO4 crystallizes in the orthorhombic Ibam space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are a spread of Rb(1)-O(1) bond distances ranging from 3.15-3.21 Å. There are two inequivalent Li sites.
