Materials Data on Pm3Y by Materials Project
Pm3Y is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pm sites. In the first Pm site, Pm is bonded to eight Pm and four equivalent Y atoms to form PmPm8Y4 cuboctahedra that share corners with twelve equivalent PmPm8Y4 cuboctahedra, edges with eight equivalent YPm12 cuboctahedra, edges with sixteen PmPm8Y4 cuboctahedra, faces with four equivalent YPm12 cuboctahedra, and faces with fourteen PmPm8Y4 cuboctahedra. All Pm–Pm bond lengths are 3.64 Å. All Pm–Y bond lengths are 3.64 Å. In the second Pm site, Pm is bonded to eight equivalent Pm and four equivalent Y atoms to form PmPm8Y4 cuboctahedra that share corners with four equivalent PmPm8Y4 cuboctahedra, corners with eight equivalent YPm12 cuboctahedra, edges with twenty-four PmPm8Y4 cuboctahedra, faces with six equivalent YPm12 cuboctahedra, and faces with twelve PmPm8Y4 cuboctahedra. All Pm–Y bond lengths are 3.64 Å. Y is bonded to twelve Pm atoms to form YPm12 cuboctahedra that share corners with four equivalent YPm12 cuboctahedra, corners with eight equivalent PmPm8Y4 cuboctahedra, edges with eight equivalent YPm12 cuboctahedra, edges with sixteen equivalent PmPm8Y4 cuboctahedra, faces with four equivalent YPm12 cuboctahedra, and faces with fourteen PmPm8Y4 cuboctahedra.
