AgGa3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Ag(1) is bonded to four equivalent Ga(2) and eight equivalent Ga(1) atoms to form AgGa12 cuboctahedra that share corners with four equivalent Ag(1)Ga12 cuboctahedra, corners with eight equivalent Ga(2)Ga8Ag4 cuboctahedra, edges with eight equivalent Ag(1)Ga12 cuboctahedra, edges with sixteen equivalent Ga(1)Ga8Ag4 cuboctahedra, faces with four equivalent Ag(1)Ga12 cuboctahedra, faces with six equivalent Ga(2)Ga8Ag4 cuboctahedra, and faces with eight equivalent Ga(1)Ga8Ag4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Ag(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form GaGa8Ag4 cuboctahedra that share corners with twelve equivalent Ga(1)Ga8Ag4 cuboctahedra, edges with eight equivalent Ag(1)Ga12 cuboctahedra, edges with eight equivalent Ga(1)Ga8Ag4 cuboctahedra, edges with eight equivalent Ga(2)Ga8Ag4 cuboctahedra, faces with four equivalent Ag(1)Ga12 cuboctahedra, faces with four equivalent Ga(2)Ga8Ag4 cuboctahedra, and faces with ten equivalent Ga(1)Ga8Ag4 cuboctahedra. In the second Ga site, Ga(2) is bonded to four equivalent Ag(1) and eight equivalent Ga(1) atoms to form GaGa8Ag4 cuboctahedra that share corners with four equivalent Ga(2)Ga8Ag4 cuboctahedra, corners with eight equivalent Ag(1)Ga12 cuboctahedra, edges with eight equivalent Ga(2)Ga8Ag4 cuboctahedra, edges with sixteen equivalent Ga(1)Ga8Ag4 cuboctahedra, faces with four equivalent Ga(2)Ga8Ag4 cuboctahedra, faces with six equivalent Ag(1)Ga12 cuboctahedra, and faces with eight equivalent Ga(1)Ga8Ag4 cuboctahedra.
