The material described by UAuGe crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ge(1) atoms. In the second U site, U(2) is bonded to six equivalent Au(1) and six equivalent Ge(1) atoms to form face-sharing UGe6Au6 cuboctahedra. Au(1) is bonded in a 6-coordinate geometry to three equivalent U(1), three equivalent U(2), and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent U(1), three equivalent U(2), and three equivalent Au(1) atoms. is represented by the CIF file [CIF]
