YbGa6 crystallizes in the tetragonal P4/nbm space group. Yb(1) is bonded to eight equivalent Ga(1) and eight equivalent Ga(2) atoms to form a mixture of distorted edge and face-sharing YbGa16 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Yb(1), two equivalent Ga(1), and five equivalent Ga(2) atoms.
YbGa6 crystallizes in the tetragonal P4/nbm space group. Yb(1) is bonded to eight equivalent Ga(1) and eight equivalent Ga(2) atoms to form a mixture of distorted edge and face-sharing YbGa16 cuboctahedra. All Yb(1)-Ga(1) bond lengths are 3.20 Å. There are four shorter (3.20 Å) and four longer (3.52 Å) Yb(1)-Ga(2) bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Ga(1), and four equivalent Ga(2) atoms. The Ga(1)-Ga(1) bond length is 2.42 Å. All Ga(1)-Ga(2) bond lengths are 2.54 Å. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Yb(1), two equivalent Ga(1), and five equivalent Ga(2) atoms. There is one shorter (2.46 Å) and four longer (2.98 Å) Ga(2)-Ga(2) bond lengths.
