The structure described by Ca3Lu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to eight equivalent Ca(1) and four equivalent Lu(1) atoms to form CaCa8Lu4 cuboctahedra that share corners with twelve equivalent Ca(1)Ca8Lu4 cuboctahedra, edges with eight equivalent Lu(1)Ca12 cuboctahedra, edges with sixteen equivalent Ca(1)Ca8Lu4 cuboctahedra, faces with four equivalent Lu(1)Ca12 cuboctahedra, and faces with fourteen equivalent Ca(1)Ca8Lu4 cuboctahedra. Lu(1) is bonded to twelve equivalent Ca(1) atoms to form LuCa12 cuboctahedra that share corners with twelve equivalent Lu(1)Ca12 cuboctahedra, edges with twenty-four equivalent Ca(1)Ca8Lu4 cuboctahedra, faces with six equivalent Lu(1)Ca12 cuboctahedra, and faces with twelve equivalent Ca(1)Ca8Lu4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
