Ag3Mg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Ag(1) atoms to form MgAg12 cuboctahedra that share corners with twelve equivalent Mg(1)Ag12 cuboctahedra, edges with twenty-four equivalent Ag(1)Mg4Ag8 cuboctahedra, faces with six equivalent Mg(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Mg4Ag8 cuboctahedra. Ag(1) is bonded to four equivalent Mg(1) and eight equivalent Ag(1) atoms to form distorted AgMg4Ag8 cuboctahedra that share corners with twelve equivalent Ag(1)Mg4Ag8 cuboctahedra, edges with eight equivalent Mg(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Mg4Ag8 cuboctahedra, faces with four equivalent Mg(1)Ag12 cuboctahedra, and faces with fourteen equivalent Ag(1)Mg4Ag8 cuboctahedra.
