Gd3Ga is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Gd(1) is bonded to eight equivalent Gd(1) and four equivalent Ga(1) atoms to form distorted GdGd8Ga4 cuboctahedra that share corners with twelve equivalent Gd(1)Gd8Ga4 cuboctahedra, edges with eight equivalent Ga(1)Gd12 cuboctahedra, edges with sixteen equivalent Gd(1)Gd8Ga4 cuboctahedra, faces with four equivalent Ga(1)Gd12 cuboctahedra, and faces with fourteen equivalent Gd(1)Gd8Ga4 cuboctahedra. Ga(1) is bonded to twelve equivalent Gd(1) atoms to form GaGd12 cuboctahedra that share corners with twelve equivalent Ga(1)Gd12 cuboctahedra, edges with twenty-four equivalent Gd(1)Gd8Ga4 cuboctahedra, faces with six equivalent Ga(1)Gd12 cuboctahedra, and faces with twelve equivalent Gd(1)Gd8Ga4 cuboctahedra.
