Materials Data on DyTm3 by Materials Project
Tm3Dy is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tm is bonded to eight equivalent Tm and four equivalent Dy atoms to form TmDy4Tm8 cuboctahedra that share corners with four equivalent DyTm12 cuboctahedra, corners with fourteen equivalent TmDy4Tm8 cuboctahedra, edges with six equivalent DyTm12 cuboctahedra, edges with twelve equivalent TmDy4Tm8 cuboctahedra, faces with four equivalent DyTm12 cuboctahedra, and faces with sixteen equivalent TmDy4Tm8 cuboctahedra. There are a spread of Tm–Tm bond distances ranging from 3.46–3.57 Å. There are two shorter (3.47 Å) and two longer (3.56 Å) Tm–Dy bond lengths. Dy is bonded to twelve equivalent Tm atoms to form DyTm12 cuboctahedra that share corners with six equivalent DyTm12 cuboctahedra, corners with twelve equivalent TmDy4Tm8 cuboctahedra, edges with eighteen equivalent TmDy4Tm8 cuboctahedra, faces with eight equivalent DyTm12 cuboctahedra, and faces with twelve equivalent TmDy4Tm8 cuboctahedra.
