The crystal structure described by RbGa3 crystallizes in the tetragonal I-4m2 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 16-coordinate geometry to four equivalent Rb(2), four equivalent Ga(2), and eight equivalent Ga(3) atoms. In the second Rb site, Rb(2) is bonded in a 19-coordinate geometry to one Rb(2), two equivalent Rb(1), two equivalent Ga(1), six equivalent Ga(3), and eight equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a body-centered cubic geometry to four equivalent Rb(2) and four equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to one Rb(1), four equivalent Rb(2), three equivalent Ga(2), and three equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to two equivalent Rb(1), three equivalent Rb(2), one Ga(1), one Ga(3), and three equivalent Ga(2) atoms. is represented by the CIF card [CIF]
