U5Ge4 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 8-coordinate geometry to two equivalent U(1) and six equivalent Ge(1) atoms. In the second U site, U(2) is bonded in a 7-coordinate geometry to two equivalent Ge(2) and five equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded to six equivalent U(2) atoms to form distorted face-sharing GeU6 octahedra. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent U(1) and five equivalent U(2) atoms.
U5Ge4 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 8-coordinate geometry to two equivalent U(1) and six equivalent Ge(1) atoms. Both U(1)-U(1) bond lengths are 2.91 Å. All U(1)-Ge(1) bond lengths are 3.08 Å. In the second U site, U(2) is bonded in a 7-coordinate geometry to two equivalent Ge(2) and five equivalent Ge(1) atoms. Both U(2)-Ge(2) bond lengths are 2.90 Å. There are a spread of U(2)-Ge(1) bond distances ranging from 2.89-2.98 Å. There are two inequivalent Ge sites.
