Materials Data on UGeAu by Materials Project

UAuGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ge atoms. All U–Au bond lengths are 3.04 Å. All U–Ge bond lengths are 3.33 Å. In the second U site, U is bonded to six equivalent Au and six equivalent Ge atoms to form face-sharing UGe6Au6 cuboctahedra. All U–Au bond lengths are 3.36 Å. All U–Ge bond lengths are 3.07 Å. Au is bonded in a 6-coordinate geometry to six U and three equivalent Ge atoms. All Au–Ge bond lengths are 2.62 Å. Ge is bonded in a 3-coordinate geometry to six U and three equivalent Au atoms.

Materials Data on UGeAu by Materials Project

UAuGe crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. U is bonded in a 11-coordinate geometry to six equivalent Au and five equivalent Ge atoms. There are a spread of U–Au bond distances ranging from 3.13–3.32 Å. There are a spread of U–Ge bond distances ranging from 3.04–3.15 Å. Au is bonded in a 10-coordinate geometry to six equivalent U, one Au, and three equivalent Ge atoms. The Au–Au bond length is 2.82 Å. There are two shorter (2.67 Å) and one longer (2.79 Å) Au–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to five equivalent U, three equivalent Au, and one Ge atom. The Ge–Ge bond length is 2.64 Å.
