Materials Data on Ag3Sb by Materials Project
Ag3Sb is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded to eight equivalent Ag1+ and four equivalent Sb3- atoms to form AgAg8Sb4 cuboctahedra that share corners with eight equivalent SbAg12 cuboctahedra, corners with ten AgAg8Sb4 cuboctahedra, edges with eighteen AgAg8Sb4 cuboctahedra, faces with six equivalent SbAg12 cuboctahedra, and faces with fourteen AgAg8Sb4 cuboctahedra. There are a spread of Ag–Ag bond distances ranging from 2.99–3.12 Å. There are two shorter (3.04 Å) and two longer (3.06 Å) Ag–Sb bond lengths. In the second Ag1+ site, Ag1+ is bonded to eight Ag1+ and four equivalent Sb3- atoms to form AgAg8Sb4 cuboctahedra that share corners with four equivalent SbAg12 cuboctahedra, corners with fourteen AgAg8Sb4 cuboctahedra, edges with six equivalent SbAg12 cuboctahedra, edges with twelve AgAg8Sb4 cuboctahedra, faces with four equivalent SbAg12 cuboctahedra, and faces with sixteen AgAg8Sb4 cuboctahedra. There are a spread of Ag–Ag bond distances ranging from 2.98–3.07 Å. There are a spread of Ag–Sb bond distances ranging from 3.01–3.13 Å. Sb3- is bonded to twelve Ag1+ atoms to form SbAg12 cuboctahedra that share corners with two equivalent SbAg12 cuboctahedra, corners with sixteen AgAg8Sb4 cuboctahedra, edges with six equivalent SbAg12 cuboctahedra, edges with twelve equivalent AgAg8Sb4 cuboctahedra, faces with six equivalent SbAg12 cuboctahedra, and faces with fourteen AgAg8Sb4 cuboctahedra.
