Materials Data on Ag3Au by Materials Project

Abstract

AuAg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Au is bonded to twelve equivalent Ag atoms to form AuAg12 cuboctahedra that share corners with twelve equivalent AuAg12 cuboctahedra, edges with twenty-four equivalent AgAg8Au4 cuboctahedra, faces with six equivalent AuAg12 cuboctahedra, and faces with twelve equivalent AgAg8Au4 cuboctahedra. All Au–Ag bond lengths are 2.94 Å. Ag is bonded to four equivalent Au and eight equivalent Ag atoms to form distorted AgAg8Au4 cuboctahedra that share corners with twelve equivalent AgAg8Au4 cuboctahedra, edges with eight equivalent AuAg12 cuboctahedra, edges with sixteen equivalent AgAg8Au4 cuboctahedra, faces with four equivalent AuAg12 cuboctahedra, and faces with fourteen equivalent AgAg8Au4 cuboctahedra. All Ag–Ag bond lengths are 2.94 Å.
