Materials Data on TmIn2Sn by Materials Project
TmIn2Sn is beta Cu3Ti-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Tm is bonded to eight equivalent In and four equivalent Sn atoms to form TmIn8Sn4 cuboctahedra that share corners with twelve equivalent TmIn8Sn4 cuboctahedra, edges with eight equivalent SnTm4In8 cuboctahedra, edges with sixteen equivalent InTm4In4Sn4 cuboctahedra, faces with four equivalent SnTm4In8 cuboctahedra, faces with six equivalent TmIn8Sn4 cuboctahedra, and faces with eight equivalent InTm4In4Sn4 cuboctahedra. All Tm–In bond lengths are 3.31 Å. All Tm–Sn bond lengths are 3.23 Å. In is bonded to four equivalent Tm, four equivalent In, and four equivalent Sn atoms to form InTm4In4Sn4 cuboctahedra that share corners with twelve equivalent InTm4In4Sn4 cuboctahedra, edges with eight equivalent TmIn8Sn4 cuboctahedra, edges with eight equivalent InTm4In4Sn4 cuboctahedra, edges with eight equivalent SnTm4In8 cuboctahedra, faces with four equivalent TmIn8Sn4 cuboctahedra, faces with four equivalent SnTm4In8 cuboctahedra, and faces with ten equivalent InTm4In4Sn4 cuboctahedra. All In–In bond lengths are 3.23 Å. All In–Sn bond lengths are 3.31 Å. Sn is bonded to four equivalent Tm and eight equivalent In atoms to form SnTm4In8 cuboctahedra that share corners with twelve equivalent SnTm4In8 cuboctahedra, edges with eight equivalent TmIn8Sn4 cuboctahedra, edges with sixteen equivalent InTm4In4Sn4 cuboctahedra, faces with four equivalent TmIn8Sn4 cuboctahedra, faces with six equivalent SnTm4In8 cuboctahedra, and faces with eight equivalent InTm4In4Sn4 cuboctahedra.
