The structure described by Tc3Pd crystallizes in the trigonal R-3m space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to three equivalent Tc(2), six equivalent Tc(1), and three equivalent Pd(1) atoms to form TcTc9Pd3 cuboctahedra that share corners with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra, edges with six equivalent Tc(2)Tc12 cuboctahedra, edges with six equivalent Pd(1)Tc6Pd6 cuboctahedra, edges with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra, faces with six equivalent Tc(2)Tc12 cuboctahedra, faces with six equivalent Tc(1)Tc9Pd3 cuboctahedra, and faces with six equivalent Pd(1)Tc6Pd6 cuboctahedra. In the second Tc site, Tc(2) is bonded to six equivalent Tc(1) and six equivalent Tc(2) atoms to form TcTc12 cuboctahedra that share corners with six equivalent Tc(2)Tc12 cuboctahedra, corners with six equivalent Pd(1)Tc6Pd6 cuboctahedra, edges with six equivalent Tc(2)Tc12 cuboctahedra, edges with six equivalent Pd(1)Tc6Pd6 cuboctahedra, edges with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra, faces with six equivalent Tc(2)Tc12 cuboctahedra, and faces with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra. Pd(1) is bonded to six equivalent Tc(1) and six equivalent Pd(1) atoms to form PdTc6Pd6 cuboctahedra that share corners with six equivalent Tc(2)Tc12 cuboctahedra, corners with six equivalent Pd(1)Tc6Pd6 cuboctahedra, edges with six equivalent Tc(2)Tc12 cuboctahedra, edges with six equivalent Pd(1)Tc6Pd6 cuboctahedra, edges with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra, faces with six equivalent Pd(1)Tc6Pd6 cuboctahedra, and faces with twelve equivalent Tc(1)Tc9Pd3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
