Materials Data on AgAu by Materials Project

Abstract

AuAg crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Au1- is bonded to six equivalent Au1- and six equivalent Ag1+ atoms to form distorted AuAg6Au6 cuboctahedra that share corners with eighteen equivalent AuAg6Au6 cuboctahedra, edges with six equivalent AuAg6Au6 cuboctahedra, edges with twelve equivalent AgAg6Au6 cuboctahedra, faces with eight equivalent AuAg6Au6 cuboctahedra, and faces with twelve equivalent AgAg6Au6 cuboctahedra. All Au–Au bond lengths are 2.94 Å. All Au–Ag bond lengths are 2.95 Å. Ag1+ is bonded to six equivalent Au1- and six equivalent Ag1+ atoms to form distorted AgAg6Au6 cuboctahedra that share corners with eighteen equivalent AgAg6Au6 cuboctahedra, edges with six equivalent AgAg6Au6 cuboctahedra, edges with twelve equivalent AuAg6Au6 cuboctahedra, faces with eight equivalent AgAg6Au6 cuboctahedra, and faces with twelve equivalent AuAg6Au6 cuboctahedra. All Ag–Ag bond lengths are 2.94 Å.
