Materials Data on PmTm3 by Materials Project

Abstract

Tm3Pm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm is bonded to eight equivalent Tm and four equivalent Pm atoms to form TmPm4Tm8 cuboctahedra that share corners with twelve equivalent TmPm4Tm8 cuboctahedra, edges with eight equivalent PmTm12 cuboctahedra, edges with sixteen equivalent TmPm4Tm8 cuboctahedra, faces with four equivalent PmTm12 cuboctahedra, and faces with fourteen equivalent TmPm4Tm8 cuboctahedra. All Tm–Tm bond lengths are 3.52 Å. All Tm–Pm bond lengths are 3.52 Å. Pm is bonded to twelve equivalent Tm atoms to form PmTm12 cuboctahedra that share corners with twelve equivalent PmTm12 cuboctahedra, edges with twenty-four equivalent TmPm4Tm8 cuboctahedra, faces with six equivalent PmTm12 cuboctahedra, and faces with twelve equivalent TmPm4Tm8 cuboctahedra.
