The material structure described by Yb3Ga8 crystallizes in the orthorhombic Immm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 14-coordinate geometry to two equivalent Ga(4), four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms. In the second Yb site, Yb(2) is bonded to four equivalent Ga(2) and eight equivalent Ga(4) atoms to form a mixture of edge and face-sharing YbGa12 cuboctahedra. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Yb(1), four equivalent Ga(1), and four equivalent Ga(3) atoms to form a mixture of distorted corner and face-sharing GaYb4Ga8 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Yb(2), four equivalent Yb(1), one Ga(3), and two equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Ga(2), and four equivalent Ga(1) atoms. In the fourth Ga site, Ga(4) is bonded in a 9-coordinate geometry to two equivalent Yb(1), four equivalent Yb(2), one Ga(4), and two equivalent Ga(2) atoms. is represented by the CIF file [CIF]
