Be25U2Ga crystallizes in the cubic Fm-3 space group. There are three inequivalent Be sites. In the first Be site, Be(3) is bonded in a cuboctahedral geometry to twelve equivalent Be(1) atoms. In the second Be site, Be(1) is bonded in a 12-coordinate geometry to one Be(3), four equivalent Be(2), five equivalent Be(1), and two equivalent U(1) atoms. In the third Be site, Be(2) is bonded in a 12-coordinate geometry to four equivalent Be(1), five equivalent Be(2), two equivalent U(1), and one Ga(1) atom. U(1) is bonded in a 24-coordinate geometry to twelve equivalent Be(1) and twelve equivalent Be(2) atoms. Ga(1) is bonded in a cuboctahedral geometry to twelve equivalent Be(2) atoms.
Be25U2Ga crystallizes in the cubic Fm-3 space group. There are three inequivalent Be sites. In the first Be site, Be(3) is bonded in a cuboctahedral geometry to twelve equivalent Be(1) atoms. All Be(3)-Be(1) bond lengths are 2.13 Å. In the second Be site, Be(1) is bonded in a 12-coordinate geometry to one Be(3), four equivalent Be(2), five equivalent Be(1), and two equivalent U(1) atoms. There are a spread of Be(1)-Be(2) bond distances ranging from 2.17-2.26 Å. There are four shorter (2.23 Å) and one longer (2.31 Å) Be(1)-Be(1) bond length. Both Be(1)-U(1) bond lengths are 3.03 Å. In the third Be site, Be(2) is bonded in a 12-coordinate geometry to four equivalent Be(1), five equivalent Be(2), two equivalent U(1), and one Ga(1) atom. There are four shorter (2.34 Å) and one longer (2.54 Å) Be(2)-Be(2) bond length. Both Be(2)-U(1) bond lengths are 2.96 Å. The Be(2)-Ga(1) bond length is 2.26 Å. U(1) is bonded in a 24-coordinate geometry to twelve equivalent Be(1) and twelve equivalent Be(2) atoms. Ga(1) is bonded in a cuboctahedral geometry to twelve equivalent Be(2) atoms.
