Materials Data on Tb3Tm by Materials Project

Abstract

TmTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm is bonded to twelve equivalent Tb atoms to form TmTb12 cuboctahedra that share corners with twelve equivalent TmTb12 cuboctahedra, edges with twenty-four equivalent TbTb8Tm4 cuboctahedra, faces with six equivalent TmTb12 cuboctahedra, and faces with twelve equivalent TbTb8Tm4 cuboctahedra. All Tm–Tb bond lengths are 3.54 Å. Tb is bonded to four equivalent Tm and eight equivalent Tb atoms to form TbTb8Tm4 cuboctahedra that share corners with twelve equivalent TbTb8Tm4 cuboctahedra, edges with eight equivalent TmTb12 cuboctahedra, edges with sixteen equivalent TbTb8Tm4 cuboctahedra, faces with four equivalent TmTb12 cuboctahedra, and faces with fourteen equivalent TbTb8Tm4 cuboctahedra. All Tb–Tb bond lengths are 3.54 Å.
