GdPm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Gd(1) is bonded to twelve equivalent Pm(1) atoms to form GdPm12 cuboctahedra that share corners with twelve equivalent Gd(1)Pm12 cuboctahedra, edges with twenty-four equivalent Pm(1)Pm8Gd4 cuboctahedra, faces with six equivalent Gd(1)Pm12 cuboctahedra, and faces with twelve equivalent Pm(1)Pm8Gd4 cuboctahedra. Pm(1) is bonded to four equivalent Gd(1) and eight equivalent Pm(1) atoms to form PmPm8Gd4 cuboctahedra that share corners with twelve equivalent Pm(1)Pm8Gd4 cuboctahedra, edges with eight equivalent Gd(1)Pm12 cuboctahedra, edges with sixteen equivalent Pm(1)Pm8Gd4 cuboctahedra, faces with four equivalent Gd(1)Pm12 cuboctahedra, and faces with fourteen equivalent Pm(1)Pm8Gd4 cuboctahedra.
