Cu3Ga is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cu(1) is bonded to eight equivalent Cu(1) and four equivalent Ga(1) atoms to form CuGa4Cu8 cuboctahedra that share corners with twelve equivalent Cu(1)Ga4Cu8 cuboctahedra, edges with eight equivalent Ga(1)Cu12 cuboctahedra, edges with sixteen equivalent Cu(1)Ga4Cu8 cuboctahedra, faces with four equivalent Ga(1)Cu12 cuboctahedra, and faces with fourteen equivalent Cu(1)Ga4Cu8 cuboctahedra. Ga(1) is bonded to twelve equivalent Cu(1) atoms to form GaCu12 cuboctahedra that share corners with twelve equivalent Ga(1)Cu12 cuboctahedra, edges with twenty-four equivalent Cu(1)Ga4Cu8 cuboctahedra, faces with six equivalent Ga(1)Cu12 cuboctahedra, and faces with twelve equivalent Cu(1)Ga4Cu8 cuboctahedra.
