Materials Data on Cd3Ga by Materials Project
Cd3Ga is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Cd is bonded to eight equivalent Cd and four equivalent Ga atoms to form CdCd8Ga4 cuboctahedra that share corners with four equivalent GaCd12 cuboctahedra, corners with fourteen equivalent CdCd8Ga4 cuboctahedra, edges with six equivalent GaCd12 cuboctahedra, edges with twelve equivalent CdCd8Ga4 cuboctahedra, faces with four equivalent GaCd12 cuboctahedra, and faces with sixteen equivalent CdCd8Ga4 cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 3.14–3.22 Å. There are two shorter (3.12 Å) and two longer (3.19 Å) Cd–Ga bond lengths. Ga is bonded to twelve equivalent Cd atoms to form GaCd12 cuboctahedra that share corners with six equivalent GaCd12 cuboctahedra, corners with twelve equivalent CdCd8Ga4 cuboctahedra, edges with eighteen equivalent CdCd8Ga4 cuboctahedra, faces with eight equivalent GaCd12 cuboctahedra, and faces with twelve equivalent CdCd8Ga4 cuboctahedra.
