Materials Data on Pm3Tm by Materials Project
TmPm3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tm is bonded to twelve equivalent Pm atoms to form TmPm12 cuboctahedra that share corners with six equivalent TmPm12 cuboctahedra, corners with twelve equivalent PmPm8Tm4 cuboctahedra, edges with eighteen equivalent PmPm8Tm4 cuboctahedra, faces with eight equivalent TmPm12 cuboctahedra, and faces with twelve equivalent PmPm8Tm4 cuboctahedra. There are six shorter (3.61 Å) and six longer (3.65 Å) Tm–Pm bond lengths. Pm is bonded to four equivalent Tm and eight equivalent Pm atoms to form PmPm8Tm4 cuboctahedra that share corners with four equivalent TmPm12 cuboctahedra, corners with fourteen equivalent PmPm8Tm4 cuboctahedra, edges with six equivalent TmPm12 cuboctahedra, edges with twelve equivalent PmPm8Tm4 cuboctahedra, faces with four equivalent TmPm12 cuboctahedra, and faces with sixteen equivalent PmPm8Tm4 cuboctahedra. There are a spread of Pm–Pm bond distances ranging from 3.62–3.67 Å.
