The material described by Gd3Ce 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 Ce(1) atoms to form GdCe4Gd8 cuboctahedra that share corners with twelve equivalent Gd(1)Ce4Gd8 cuboctahedra, edges with eight equivalent Ce(1)Gd12 cuboctahedra, edges with sixteen equivalent Gd(1)Ce4Gd8 cuboctahedra, faces with four equivalent Ce(1)Gd12 cuboctahedra, and faces with fourteen equivalent Gd(1)Ce4Gd8 cuboctahedra. Ce(1) is bonded to twelve equivalent Gd(1) atoms to form CeGd12 cuboctahedra that share corners with twelve equivalent Ce(1)Gd12 cuboctahedra, edges with twenty-four equivalent Gd(1)Ce4Gd8 cuboctahedra, faces with six equivalent Ce(1)Gd12 cuboctahedra, and faces with twelve equivalent Gd(1)Ce4Gd8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
