The structure described by CaTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to twelve equivalent Tb(1) atoms to form CaTb12 cuboctahedra that share corners with twelve equivalent Ca(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Ca4Tb8 cuboctahedra, faces with six equivalent Ca(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Ca4Tb8 cuboctahedra. Tb(1) is bonded to four equivalent Ca(1) and eight equivalent Tb(1) atoms to form TbCa4Tb8 cuboctahedra that share corners with twelve equivalent Tb(1)Ca4Tb8 cuboctahedra, edges with eight equivalent Ca(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Ca4Tb8 cuboctahedra, faces with four equivalent Ca(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Ca4Tb8 cuboctahedra. is represented by the CIF card [CIF]
