Materials Data on Pm3Dy by Materials Project

Abstract

DyPm3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Dy is bonded to twelve equivalent Pm atoms to form DyPm12 cuboctahedra that share corners with six equivalent DyPm12 cuboctahedra, corners with twelve equivalent PmPm8Dy4 cuboctahedra, edges with eighteen equivalent PmPm8Dy4 cuboctahedra, faces with eight equivalent DyPm12 cuboctahedra, and faces with twelve equivalent PmPm8Dy4 cuboctahedra. There are six shorter (3.63 Å) and six longer (3.65 Å) Dy–Pm bond lengths. Pm is bonded to four equivalent Dy and eight equivalent Pm atoms to form PmPm8Dy4 cuboctahedra that share corners with four equivalent DyPm12 cuboctahedra, corners with fourteen equivalent PmPm8Dy4 cuboctahedra, edges with six equivalent DyPm12 cuboctahedra, edges with twelve equivalent PmPm8Dy4 cuboctahedra, faces with four equivalent DyPm12 cuboctahedra, and faces with sixteen equivalent PmPm8Dy4 cuboctahedra. There are six shorter (3.64 Å) and two longer (3.66 Å) Pm–Pm bond lengths.
