Materials Data on MgAg3 by Materials Project

Abstract

Ag3Mg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg is bonded to twelve equivalent Ag atoms to form MgAg12 cuboctahedra that share corners with twelve equivalent MgAg12 cuboctahedra, edges with twenty-four equivalent AgMg4Ag8 cuboctahedra, faces with six equivalent MgAg12 cuboctahedra, and faces with twelve equivalent AgMg4Ag8 cuboctahedra. All Mg–Ag bond lengths are 2.95 Å. Ag is bonded to four equivalent Mg and eight equivalent Ag atoms to form distorted AgMg4Ag8 cuboctahedra that share corners with twelve equivalent AgMg4Ag8 cuboctahedra, edges with eight equivalent MgAg12 cuboctahedra, edges with sixteen equivalent AgMg4Ag8 cuboctahedra, faces with four equivalent MgAg12 cuboctahedra, and faces with fourteen equivalent AgMg4Ag8 cuboctahedra. All Ag–Ag bond lengths are 2.95 Å.
