Materials Data on PmEr3 by Materials Project

Abstract

Er3Pm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded to eight equivalent Er and four equivalent Pm atoms to form ErPm4Er8 cuboctahedra that share corners with twelve equivalent ErPm4Er8 cuboctahedra, edges with eight equivalent PmEr12 cuboctahedra, edges with sixteen equivalent ErPm4Er8 cuboctahedra, faces with four equivalent PmEr12 cuboctahedra, and faces with fourteen equivalent ErPm4Er8 cuboctahedra. All Er–Er bond lengths are 3.54 Å. All Er–Pm bond lengths are 3.54 Å. Pm is bonded to twelve equivalent Er atoms to form PmEr12 cuboctahedra that share corners with twelve equivalent PmEr12 cuboctahedra, edges with twenty-four equivalent ErPm4Er8 cuboctahedra, faces with six equivalent PmEr12 cuboctahedra, and faces with twelve equivalent ErPm4Er8 cuboctahedra.
