The compound described by PtPd is alpha La-derived structured and crystallizes in the trigonal R-3m space group. Pt(1) is bonded to six equivalent Pt(1) and six equivalent Pd(1) atoms to form PtPd6Pt6 cuboctahedra that share corners with twelve equivalent Pt(1)Pd6Pt6 cuboctahedra, edges with twelve equivalent Pt(1)Pd6Pt6 cuboctahedra, edges with twelve equivalent Pd(1)Pd6Pt6 cuboctahedra, faces with six equivalent Pt(1)Pd6Pt6 cuboctahedra, and faces with twelve equivalent Pd(1)Pd6Pt6 cuboctahedra. Pd(1) is bonded to six equivalent Pt(1) and six equivalent Pd(1) atoms to form PdPd6Pt6 cuboctahedra that share corners with twelve equivalent Pd(1)Pd6Pt6 cuboctahedra, edges with twelve equivalent Pt(1)Pd6Pt6 cuboctahedra, edges with twelve equivalent Pd(1)Pd6Pt6 cuboctahedra, faces with six equivalent Pd(1)Pd6Pt6 cuboctahedra, and faces with twelve equivalent Pt(1)Pd6Pt6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
