Materials Data on Tb3Tm by Materials Project
TmTb3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tm is bonded to twelve Tb atoms to form TmTb12 cuboctahedra that share corners with four equivalent TmTb12 cuboctahedra, corners with eight 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 TbTb8Tm4 cuboctahedra. There are four shorter (3.54 Å) and eight longer (3.55 Å) Tm–Tb bond lengths. There are two inequivalent Tb sites. In the first Tb site, Tb is bonded to four equivalent Tm and eight Tb atoms to form TbTb8Tm4 cuboctahedra that share corners with twelve equivalent TbTb8Tm4 cuboctahedra, edges with eight equivalent TmTb12 cuboctahedra, edges with sixteen TbTb8Tm4 cuboctahedra, faces with four equivalent TmTb12 cuboctahedra, and faces with fourteen TbTb8Tm4 cuboctahedra. There are four shorter (3.54 Å) and four longer (3.55 Å) Tb–Tb bond lengths. In the second Tb site, Tb is bonded to four equivalent Tm and eight equivalent Tb atoms to form TbTb8Tm4 cuboctahedra that share corners with four equivalent TbTb8Tm4 cuboctahedra, corners with eight equivalent TmTb12 cuboctahedra, edges with twenty-four TbTb8Tm4 cuboctahedra, faces with six equivalent TmTb12 cuboctahedra, and faces with twelve TbTb8Tm4 cuboctahedra.
