Materials Data on Dy3Y by Materials Project

Dy3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Dy is bonded to eight equivalent Dy and four equivalent Y atoms to form DyDy8Y4 cuboctahedra that share corners with twelve equivalent DyDy8Y4 cuboctahedra, edges with eight equivalent YDy12 cuboctahedra, edges with sixteen equivalent DyDy8Y4 cuboctahedra, faces with four equivalent YDy12 cuboctahedra, and faces with fourteen equivalent DyDy8Y4 cuboctahedra. All Dy–Dy bond lengths are 3.56 Å. All Dy–Y bond lengths are 3.56 Å. Y is bonded to twelve equivalent Dy atoms to form YDy12 cuboctahedra that share corners with twelve equivalent YDy12 cuboctahedra, edges with twenty-four equivalent DyDy8Y4 cuboctahedra, faces with six equivalent YDy12 cuboctahedra, and faces with twelve equivalent DyDy8Y4 cuboctahedra.

Materials Data on Dy3Y by Materials Project

Dy3Y is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded to eight Dy and four equivalent Y atoms to form DyDy8Y4 cuboctahedra that share corners with twelve equivalent DyDy8Y4 cuboctahedra, edges with eight equivalent YDy12 cuboctahedra, edges with sixteen DyDy8Y4 cuboctahedra, faces with four equivalent YDy12 cuboctahedra, and faces with fourteen DyDy8Y4 cuboctahedra. There are four shorter (3.55 Å) and four longer (3.56 Å) Dy–Dy bond lengths. All Dy–Y bond lengths are 3.56 Å. In the second Dy site, Dy is bonded to eight equivalent Dy and four equivalent Y atoms to form DyDy8Y4 cuboctahedra that share corners with four equivalent DyDy8Y4 cuboctahedra, corners with eight equivalent YDy12 cuboctahedra, edges with twenty-four DyDy8Y4 cuboctahedra, faces with six equivalent YDy12 cuboctahedra, and faces with twelve DyDy8Y4 cuboctahedra. All Dy–Y bond lengths are 3.55 Å. Y is bonded to twelve Dy atoms to form YDy12 cuboctahedra that share corners with four equivalent YDy12 cuboctahedra, corners with eight equivalent DyDy8Y4 cuboctahedra, edges with eight equivalent YDy12 cuboctahedra, edges with sixteen equivalent DyDy8Y4 cuboctahedra, faces with four equivalent YDy12 cuboctahedra, and faces with fourteen DyDy8Y4 cuboctahedra.
