Materials Data on Gd3Cd by Materials Project
Gd3Cd is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Gd is bonded to eight equivalent Gd and four equivalent Cd atoms to form distorted GdGd8Cd4 cuboctahedra that share corners with four equivalent CdGd12 cuboctahedra, corners with fourteen equivalent GdGd8Cd4 cuboctahedra, edges with six equivalent CdGd12 cuboctahedra, edges with twelve equivalent GdGd8Cd4 cuboctahedra, faces with four equivalent CdGd12 cuboctahedra, and faces with sixteen equivalent GdGd8Cd4 cuboctahedra. There are a spread of Gd–Gd bond distances ranging from 3.38–3.62 Å. There are two shorter (3.39 Å) and two longer (3.50 Å) Gd–Cd bond lengths. Cd is bonded to twelve equivalent Gd atoms to form CdGd12 cuboctahedra that share corners with six equivalent CdGd12 cuboctahedra, corners with twelve equivalent GdGd8Cd4 cuboctahedra, edges with eighteen equivalent GdGd8Cd4 cuboctahedra, faces with eight equivalent CdGd12 cuboctahedra, and faces with twelve equivalent GdGd8Cd4 cuboctahedra.
