Materials Data on Pm3Sm by Materials Project
SmPm3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sm is bonded to twelve equivalent Pm atoms to form SmPm12 cuboctahedra that share corners with six equivalent SmPm12 cuboctahedra, corners with twelve equivalent PmPm8Sm4 cuboctahedra, edges with eighteen equivalent PmPm8Sm4 cuboctahedra, faces with eight equivalent SmPm12 cuboctahedra, and faces with twelve equivalent PmPm8Sm4 cuboctahedra. All Sm–Pm bond lengths are 3.66 Å. Pm is bonded to four equivalent Sm and eight equivalent Pm atoms to form PmPm8Sm4 cuboctahedra that share corners with four equivalent SmPm12 cuboctahedra, corners with fourteen equivalent PmPm8Sm4 cuboctahedra, edges with six equivalent SmPm12 cuboctahedra, edges with twelve equivalent PmPm8Sm4 cuboctahedra, faces with four equivalent SmPm12 cuboctahedra, and faces with sixteen equivalent PmPm8Sm4 cuboctahedra. All Pm–Pm bond lengths are 3.66 Å.
