Gd3Y 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 Y(1) atoms to form GdGd8Y4 cuboctahedra that share corners with twelve equivalent Gd(1)Gd8Y4 cuboctahedra, edges with eight equivalent Y(1)Gd12 cuboctahedra, edges with sixteen equivalent Gd(1)Gd8Y4 cuboctahedra, faces with four equivalent Y(1)Gd12 cuboctahedra, and faces with fourteen equivalent Gd(1)Gd8Y4 cuboctahedra. Y(1) is bonded to twelve equivalent Gd(1) atoms to form YGd12 cuboctahedra that share corners with twelve equivalent Y(1)Gd12 cuboctahedra, edges with twenty-four equivalent Gd(1)Gd8Y4 cuboctahedra, faces with six equivalent Y(1)Gd12 cuboctahedra, and faces with twelve equivalent Gd(1)Gd8Y4 cuboctahedra.
