The structure described by AgGe3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Ag(1) is bonded to four equivalent Ge(2) and eight equivalent Ge(1) atoms to form AgGe12 cuboctahedra that share corners with four equivalent Ag(1)Ge12 cuboctahedra, corners with eight equivalent Ge(2)Ag4Ge8 cuboctahedra, edges with eight equivalent Ag(1)Ge12 cuboctahedra, edges with sixteen equivalent Ge(1)Ag4Ge8 cuboctahedra, faces with four equivalent Ag(1)Ge12 cuboctahedra, faces with six equivalent Ge(2)Ag4Ge8 cuboctahedra, and faces with eight equivalent Ge(1)Ag4Ge8 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ag(1), four equivalent Ge(1), and four equivalent Ge(2) atoms to form GeAg4Ge8 cuboctahedra that share corners with twelve equivalent Ge(1)Ag4Ge8 cuboctahedra, edges with eight equivalent Ag(1)Ge12 cuboctahedra, edges with eight equivalent Ge(1)Ag4Ge8 cuboctahedra, edges with eight equivalent Ge(2)Ag4Ge8 cuboctahedra, faces with four equivalent Ag(1)Ge12 cuboctahedra, faces with four equivalent Ge(2)Ag4Ge8 cuboctahedra, and faces with ten equivalent Ge(1)Ag4Ge8 cuboctahedra. In the second Ge site, Ge(2) is bonded to four equivalent Ag(1) and eight equivalent Ge(1) atoms to form distorted GeAg4Ge8 cuboctahedra that share corners with four equivalent Ge(2)Ag4Ge8 cuboctahedra, corners with eight equivalent Ag(1)Ge12 cuboctahedra, edges with eight equivalent Ge(2)Ag4Ge8 cuboctahedra, edges with sixteen equivalent Ge(1)Ag4Ge8 cuboctahedra, faces with four equivalent Ge(2)Ag4Ge8 cuboctahedra, faces with six equivalent Ag(1)Ge12 cuboctahedra, and faces with eight equivalent Ge(1)Ag4Ge8 cuboctahedra. is represented by the CIF file [CIF]
