Materials Data on PmHo by Materials Project
HoPm crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ho is bonded to six equivalent Ho and six equivalent Pm atoms to form HoPm6Ho6 cuboctahedra that share corners with eighteen equivalent HoPm6Ho6 cuboctahedra, edges with six equivalent HoPm6Ho6 cuboctahedra, edges with twelve equivalent PmPm6Ho6 cuboctahedra, faces with eight equivalent HoPm6Ho6 cuboctahedra, and faces with twelve equivalent PmPm6Ho6 cuboctahedra. All Ho–Ho bond lengths are 3.64 Å. All Ho–Pm bond lengths are 3.57 Å. Pm is bonded to six equivalent Ho and six equivalent Pm atoms to form PmPm6Ho6 cuboctahedra that share corners with eighteen equivalent PmPm6Ho6 cuboctahedra, edges with six equivalent PmPm6Ho6 cuboctahedra, edges with twelve equivalent HoPm6Ho6 cuboctahedra, faces with eight equivalent PmPm6Ho6 cuboctahedra, and faces with twelve equivalent HoPm6Ho6 cuboctahedra. All Pm–Pm bond lengths are 3.64 Å.
