Ba10Ga crystallizes in the cubic Fd-3m space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted linear geometry to two equivalent Ga(1) atoms. In the second Ba site, Ba(2) is bonded in a 1-coordinate geometry to two equivalent Ba(3) and one Ga(1) atom. In the third Ba site, Ba(3) is bonded to twelve equivalent Ba(2) atoms to form BaBa12 cuboctahedra that share edges with six equivalent Ba(3)Ba12 cuboctahedra and edges with six equivalent Ga(1)Ba12 cuboctahedra. Ga(1) is bonded to six equivalent Ba(1) and six equivalent Ba(2) atoms to form GaBa12 cuboctahedra that share corners with six equivalent Ga(1)Ba12 cuboctahedra and edges with six equivalent Ba(3)Ba12 cuboctahedra.
Ba10Ga crystallizes in the cubic Fd-3m space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted linear geometry to two equivalent Ga(1) atoms. Both Ba(1)-Ga(1) bond lengths are 3.86 Å. In the second Ba site, Ba(2) is bonded in a 1-coordinate geometry to two equivalent Ba(3) and one Ga(1) atom. Both Ba(2)-Ba(3) bond lengths are 4.76 Å. The Ba(2)-Ga(1) bond length is 4.03 Å. In the third Ba site, Ba(3) is bonded to twelve equivalent Ba(2) atoms to form BaBa12 cuboctahedra that share edges with six equivalent Ba(3)Ba12 cuboctahedra and edges with six equivalent Ga(1)Ba12 cuboctahedra.
