Materials Data on Pm3Er by Materials Project
ErPm3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Er is bonded to twelve equivalent Pm atoms to form ErPm12 cuboctahedra that share corners with six equivalent ErPm12 cuboctahedra, corners with twelve equivalent PmPm8Er4 cuboctahedra, edges with eighteen equivalent PmPm8Er4 cuboctahedra, faces with eight equivalent ErPm12 cuboctahedra, and faces with twelve equivalent PmPm8Er4 cuboctahedra. There are six shorter (3.60 Å) and six longer (3.66 Å) Er–Pm bond lengths. Pm is bonded to four equivalent Er and eight equivalent Pm atoms to form PmPm8Er4 cuboctahedra that share corners with four equivalent ErPm12 cuboctahedra, corners with fourteen equivalent PmPm8Er4 cuboctahedra, edges with six equivalent ErPm12 cuboctahedra, edges with twelve equivalent PmPm8Er4 cuboctahedra, faces with four equivalent ErPm12 cuboctahedra, and faces with sixteen equivalent PmPm8Er4 cuboctahedra. There are a spread of Pm–Pm bond distances ranging from 3.61–3.67 Å.
