Materials Data on Gd3Y by Materials Project

Gd3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Gd is bonded to eight equivalent Gd and four equivalent Y atoms to form GdGd8Y4 cuboctahedra that share corners with twelve equivalent GdGd8Y4 cuboctahedra, edges with eight equivalent YGd12 cuboctahedra, edges with sixteen equivalent GdGd8Y4 cuboctahedra, faces with four equivalent YGd12 cuboctahedra, and faces with fourteen equivalent GdGd8Y4 cuboctahedra. All Gd–Gd bond lengths are 3.57 Å. All Gd–Y bond lengths are 3.57 Å. Y is bonded to twelve equivalent Gd atoms to form YGd12 cuboctahedra that share corners with twelve equivalent YGd12 cuboctahedra, edges with twenty-four equivalent GdGd8Y4 cuboctahedra, faces with six equivalent YGd12 cuboctahedra, and faces with twelve equivalent GdGd8Y4 cuboctahedra.

Materials Data on GdY3 by Materials Project

GdY3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd is bonded to twelve Y atoms to form GdY12 cuboctahedra that share corners with four equivalent GdY12 cuboctahedra, corners with eight equivalent YGd4Y8 cuboctahedra, edges with eight equivalent GdY12 cuboctahedra, edges with sixteen equivalent YGd4Y8 cuboctahedra, faces with four equivalent GdY12 cuboctahedra, and faces with fourteen YGd4Y8 cuboctahedra. All Gd–Y bond lengths are 3.59 Å. There are two inequivalent Y sites. In the first Y site, Y is bonded to four equivalent Gd and eight Y atoms to form YGd4Y8 cuboctahedra that share corners with twelve equivalent YGd4Y8 cuboctahedra, edges with eight equivalent GdY12 cuboctahedra, edges with sixteen YGd4Y8 cuboctahedra, faces with four equivalent GdY12 cuboctahedra, and faces with fourteen YGd4Y8 cuboctahedra. All Y–Y bond lengths are 3.59 Å. In the second Y site, Y is bonded to four equivalent Gd and eight equivalent Y atoms to form YGd4Y8 cuboctahedra that share corners with four equivalent YGd4Y8 cuboctahedra, corners with eight equivalent GdY12 cuboctahedra, edges with twenty-four YGd4Y8 cuboctahedra, faces with six equivalent GdY12 cuboctahedra, and faces with twelve YGd4Y8 cuboctahedra.
