Au3Ge is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded to four equivalent Au(2) and four equivalent Ge(1) atoms to form a mixture of distorted edge, face, and corner-sharing AuGe4Au4 tetrahedra. In the second Au site, Au(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Au(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a body-centered cubic geometry to six equivalent Au(2) and eight equivalent Au(1) atoms.

In the first Au site, Au(1) is bonded to four equivalent Au(2) and four equivalent Ge(1) atoms to form a mixture of distorted edge, face, and corner-sharing AuGe4Au4 tetrahedra. All Au(1)-Au(2) bond lengths are 2.85 Å. All Au(1)-Ge(1) bond lengths are 2.85 Å. In the second Au site, Au(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Au(1) and six equivalent Ge(1) atoms. All Au(2)-Ge(1) bond lengths are 3.29 Å. Ge(1) is bonded in a body-centered cubic geometry to six equivalent Au(2) and eight equivalent Au(1) atoms.
