Materials Data on Co2Pd by Materials Project

Abstract

PdCo2 is beta-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Co is bonded to nine equivalent Co and three equivalent Pd atoms to form CoCo9Pd3 cuboctahedra that share corners with three equivalent PdCo6Pd6 cuboctahedra, corners with nine equivalent CoCo9Pd3 cuboctahedra, edges with nine equivalent PdCo6Pd6 cuboctahedra, edges with fifteen equivalent CoCo9Pd3 cuboctahedra, faces with six equivalent PdCo6Pd6 cuboctahedra, and faces with twelve equivalent CoCo9Pd3 cuboctahedra. There are three shorter (2.43 Å) and six longer (2.64 Å) Co–Co bond lengths. All Co–Pd bond lengths are 2.68 Å. Pd is bonded to six equivalent Co and six equivalent Pd atoms to form PdCo6Pd6 cuboctahedra that share corners with six equivalent CoCo9Pd3 cuboctahedra, corners with six equivalent PdCo6Pd6 cuboctahedra, edges with six equivalent PdCo6Pd6 cuboctahedra, edges with eighteen equivalent CoCo9Pd3 cuboctahedra, faces with six equivalent PdCo6Pd6 cuboctahedra, and faces with twelve equivalent CoCo9Pd3 cuboctahedra. All Pd–Pd bond lengths are 2.64 Å.
