Materials Data on Pm3Sc by Materials Project
Pm3Sc is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pm is bonded to eight equivalent Pm and four equivalent Sc atoms to form distorted PmPm8Sc4 cuboctahedra that share corners with four equivalent ScPm12 cuboctahedra, corners with fourteen equivalent PmPm8Sc4 cuboctahedra, edges with six equivalent ScPm12 cuboctahedra, edges with twelve equivalent PmPm8Sc4 cuboctahedra, faces with four equivalent ScPm12 cuboctahedra, and faces with sixteen equivalent PmPm8Sc4 cuboctahedra. There are a spread of Pm–Pm bond distances ranging from 3.54–3.67 Å. There are two shorter (3.52 Å) and two longer (3.61 Å) Pm–Sc bond lengths. Sc is bonded to twelve equivalent Pm atoms to form ScPm12 cuboctahedra that share corners with six equivalent ScPm12 cuboctahedra, corners with twelve equivalent PmPm8Sc4 cuboctahedra, edges with eighteen equivalent PmPm8Sc4 cuboctahedra, faces with eight equivalent ScPm12 cuboctahedra, and faces with twelve equivalent PmPm8Sc4 cuboctahedra.
