Materials Data on PmHo3 by Materials Project

Abstract

Ho3Pm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ho is bonded to eight equivalent Ho and four equivalent Pm atoms to form HoPm4Ho8 cuboctahedra that share corners with twelve equivalent HoPm4Ho8 cuboctahedra, edges with eight equivalent PmHo12 cuboctahedra, edges with sixteen equivalent HoPm4Ho8 cuboctahedra, faces with four equivalent PmHo12 cuboctahedra, and faces with fourteen equivalent HoPm4Ho8 cuboctahedra. All Ho–Ho bond lengths are 3.55 Å. All Ho–Pm bond lengths are 3.55 Å. Pm is bonded to twelve equivalent Ho atoms to form PmHo12 cuboctahedra that share corners with twelve equivalent PmHo12 cuboctahedra, edges with twenty-four equivalent HoPm4Ho8 cuboctahedra, faces with six equivalent PmHo12 cuboctahedra, and faces with twelve equivalent HoPm4Ho8 cuboctahedra.
