The structure described by CsGa7 crystallizes in the trigonal R-3m space group. Cs(1) is bonded in a 15-coordinate geometry to three equivalent Ga(2), three equivalent Ga(3), and nine equivalent Ga(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 7-coordinate geometry to three equivalent Cs(1), one Ga(2), and three equivalent Ga(1) atoms. In the second Ga site, Ga(3) is bonded in a 8-coordinate geometry to one Cs(1), three equivalent Ga(1), and four equivalent Ga(3) atoms. In the third Ga site, Ga(1) is bonded in a 9-coordinate geometry to three equivalent Cs(1), one Ga(2), two equivalent Ga(1), and three equivalent Ga(3) atoms. is represented by the CIF file [CIF]
