The material described by AuGe3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Au(1) is bonded to four equivalent Ge(2) and eight equivalent Ge(1) atoms to form AuGe12 cuboctahedra that share corners with four equivalent Au(1)Ge12 cuboctahedra, edges with eight equivalent Au(1)Ge12 cuboctahedra, edges with sixteen equivalent Ge(1)Ge8Au4 cuboctahedra, faces with four equivalent Au(1)Ge12 cuboctahedra, and faces with eight equivalent Ge(1)Ge8Au4 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Au(1), four equivalent Ge(1), and four equivalent Ge(2) atoms to form distorted GeGe8Au4 cuboctahedra that share corners with twelve equivalent Ge(1)Ge8Au4 cuboctahedra, edges with eight equivalent Au(1)Ge12 cuboctahedra, edges with eight equivalent Ge(1)Ge8Au4 cuboctahedra, faces with four equivalent Au(1)Ge12 cuboctahedra, and faces with ten equivalent Ge(1)Ge8Au4 cuboctahedra. In the second Ge site, Ge(2) is bonded in a square co-planar geometry to four equivalent Au(1) and eight equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
