Title: Materials Data on Pm3Sm by Materials Project

Abstract

SmPm3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm is bonded to twelve Pm atoms to form SmPm12 cuboctahedra that share corners with four equivalent SmPm12 cuboctahedra, corners with eight equivalent PmPm8Sm4 cuboctahedra, edges with eight equivalent SmPm12 cuboctahedra, edges with sixteen equivalent PmPm8Sm4 cuboctahedra, faces with four equivalent SmPm12 cuboctahedra, and faces with fourteen PmPm8Sm4 cuboctahedra. All Sm–Pm bond lengths are 3.65 Å. There are two inequivalent Pm sites. In the first Pm site, Pm is bonded to four equivalent Sm and eight Pm atoms to form PmPm8Sm4 cuboctahedra that share corners with twelve equivalent PmPm8Sm4 cuboctahedra, edges with eight equivalent SmPm12 cuboctahedra, edges with sixteen PmPm8Sm4 cuboctahedra, faces with four equivalent SmPm12 cuboctahedra, and faces with fourteen PmPm8Sm4 cuboctahedra. All Pm–Pm bond lengths are 3.65 Å. In the second Pm site, Pm is bonded to four equivalent Sm and eight equivalent Pm atoms to form PmPm8Sm4 cuboctahedra that share corners with four equivalent PmPm8Sm4 cuboctahedra, corners with eight equivalent SmPm12 cuboctahedra, edges with twenty-four PmPm8Sm4 cuboctahedra, faces with six equivalent SmPm12 cuboctahedra, and faces with twelve PmPm8Sm4 cuboctahedra.
