Ca3Cd 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 Cd(1) atoms to form distorted CaCa8Cd4 cuboctahedra that share corners with twelve equivalent Ca(1)Ca8Cd4 cuboctahedra, edges with eight equivalent Cd(1)Ca12 cuboctahedra, edges with sixteen equivalent Ca(1)Ca8Cd4 cuboctahedra, faces with four equivalent Cd(1)Ca12 cuboctahedra, and faces with fourteen equivalent Ca(1)Ca8Cd4 cuboctahedra. Cd(1) is bonded to twelve equivalent Ca(1) atoms to form CdCa12 cuboctahedra that share corners with twelve equivalent Cd(1)Ca12 cuboctahedra, edges with twenty-four equivalent Ca(1)Ca8Cd4 cuboctahedra, faces with six equivalent Cd(1)Ca12 cuboctahedra, and faces with twelve equivalent Ca(1)Ca8Cd4 cuboctahedra.
