Materials Data on Pm3Y by Materials Project

Abstract

Pm3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pm is bonded to eight equivalent 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 equivalent PmPm8Y4 cuboctahedra, faces with four equivalent YPm12 cuboctahedra, and faces with fourteen equivalent PmPm8Y4 cuboctahedra. All Pm–Pm bond lengths are 3.63 Å. All Pm–Y bond lengths are 3.63 Å. Y is bonded to twelve equivalent Pm atoms to form YPm12 cuboctahedra that share corners with twelve equivalent YPm12 cuboctahedra, edges with twenty-four equivalent PmPm8Y4 cuboctahedra, faces with six equivalent YPm12 cuboctahedra, and faces with twelve equivalent PmPm8Y4 cuboctahedra.
