The material described by CuGa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cu(1) is bonded to twelve equivalent Ga(1) atoms to form CuGa12 cuboctahedra that share corners with twelve equivalent Cu(1)Ga12 cuboctahedra, edges with twenty-four equivalent Ga(1)Ga8Cu4 cuboctahedra, faces with six equivalent Cu(1)Ga12 cuboctahedra, and faces with twelve equivalent Ga(1)Ga8Cu4 cuboctahedra. Ga(1) is bonded to four equivalent Cu(1) and eight equivalent Ga(1) atoms to form GaGa8Cu4 cuboctahedra that share corners with twelve equivalent Ga(1)Ga8Cu4 cuboctahedra, edges with eight equivalent Cu(1)Ga12 cuboctahedra, edges with sixteen equivalent Ga(1)Ga8Cu4 cuboctahedra, faces with four equivalent Cu(1)Ga12 cuboctahedra, and faces with fourteen equivalent Ga(1)Ga8Cu4 cuboctahedra. is represented by the CIF file [CIF]
