Materials Data on YbDy3 by Materials Project

YbDy3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Yb is bonded to twelve equivalent Dy atoms to form YbDy12 cuboctahedra that share corners with twelve equivalent YbDy12 cuboctahedra, edges with twenty-four equivalent DyYb4Dy8 cuboctahedra, faces with six equivalent YbDy12 cuboctahedra, and faces with twelve equivalent DyYb4Dy8 cuboctahedra. All Yb–Dy bond lengths are 3.58 Å. Dy is bonded to four equivalent Yb and eight equivalent Dy atoms to form DyYb4Dy8 cuboctahedra that share corners with twelve equivalent DyYb4Dy8 cuboctahedra, edges with eight equivalent YbDy12 cuboctahedra, edges with sixteen equivalent DyYb4Dy8 cuboctahedra, faces with four equivalent YbDy12 cuboctahedra, and faces with fourteen equivalent DyYb4Dy8 cuboctahedra. All Dy–Dy bond lengths are 3.58 Å.

Materials Data on YbDy3 by Materials Project

YbDy3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb is bonded to twelve Dy atoms to form YbDy12 cuboctahedra that share corners with four equivalent YbDy12 cuboctahedra, corners with eight equivalent DyYb4Dy8 cuboctahedra, edges with eight equivalent YbDy12 cuboctahedra, edges with sixteen equivalent DyYb4Dy8 cuboctahedra, faces with four equivalent YbDy12 cuboctahedra, and faces with fourteen DyYb4Dy8 cuboctahedra. All Yb–Dy bond lengths are 3.58 Å. There are two inequivalent Dy sites. In the first Dy site, Dy is bonded to four equivalent Yb and eight Dy atoms to form DyYb4Dy8 cuboctahedra that share corners with twelve equivalent DyYb4Dy8 cuboctahedra, edges with eight equivalent YbDy12 cuboctahedra, edges with sixteen DyYb4Dy8 cuboctahedra, faces with four equivalent YbDy12 cuboctahedra, and faces with fourteen DyYb4Dy8 cuboctahedra. All Dy–Dy bond lengths are 3.58 Å. In the second Dy site, Dy is bonded to four equivalent Yb and eight equivalent Dy atoms to form DyYb4Dy8 cuboctahedra that share corners with four equivalent DyYb4Dy8 cuboctahedra, corners with eight equivalent YbDy12 cuboctahedra, edges with twenty-four DyYb4Dy8 cuboctahedra, faces with six equivalent YbDy12 cuboctahedra, and faces with twelve DyYb4Dy8 cuboctahedra.

Materials Data on Yb3Dy by Materials Project

Yb3Dy is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to eight equivalent Yb and four equivalent Dy atoms to form YbYb8Dy4 cuboctahedra that share corners with four equivalent DyYb12 cuboctahedra, corners with fourteen equivalent YbYb8Dy4 cuboctahedra, edges with six equivalent DyYb12 cuboctahedra, edges with twelve equivalent YbYb8Dy4 cuboctahedra, faces with four equivalent DyYb12 cuboctahedra, and faces with sixteen equivalent YbYb8Dy4 cuboctahedra. There are a spread of Yb–Yb bond distances ranging from 3.67–3.85 Å. There are two shorter (3.69 Å) and two longer (3.76 Å) Yb–Dy bond lengths. Dy is bonded to twelve equivalent Yb atoms to form DyYb12 cuboctahedra that share corners with six equivalent DyYb12 cuboctahedra, corners with twelve equivalent YbYb8Dy4 cuboctahedra, edges with eighteen equivalent YbYb8Dy4 cuboctahedra, faces with eight equivalent DyYb12 cuboctahedra, and faces with twelve equivalent YbYb8Dy4 cuboctahedra.
