Fe2Pd crystallizes in the trigonal P-3m1 space group. Fe(1) is bonded to nine equivalent Fe(1) and three equivalent Pd(1) atoms to form distorted FeFe9Pd3 cuboctahedra that share corners with three equivalent Pd(1)Fe6Pd6 cuboctahedra, corners with nine equivalent Fe(1)Fe9Pd3 cuboctahedra, edges with nine equivalent Pd(1)Fe6Pd6 cuboctahedra, edges with fifteen equivalent Fe(1)Fe9Pd3 cuboctahedra, faces with six equivalent Pd(1)Fe6Pd6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe9Pd3 cuboctahedra. Pd(1) is bonded to six equivalent Fe(1) and six equivalent Pd(1) atoms to form distorted PdFe6Pd6 cuboctahedra that share corners with six equivalent Fe(1)Fe9Pd3 cuboctahedra, corners with six equivalent Pd(1)Fe6Pd6 cuboctahedra, edges with six equivalent Pd(1)Fe6Pd6 cuboctahedra, edges with eighteen equivalent Fe(1)Fe9Pd3 cuboctahedra, faces with six equivalent Pd(1)Fe6Pd6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe9Pd3 cuboctahedra.
