The material described by U5Ge3 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 5-coordinate geometry to five equivalent Ge(1) atoms. In the second U site, U(2) is bonded in a 8-coordinate geometry to two equivalent U(2) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent U(2) and five equivalent U(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
