Fe3Ag is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Ag(1) atoms to form FeFe8Ag4 cuboctahedra that share corners with twelve equivalent Fe(1)Fe8Ag4 cuboctahedra, edges with eight equivalent Ag(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Fe8Ag4 cuboctahedra, faces with four equivalent Ag(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Fe8Ag4 cuboctahedra. Ag(1) is bonded to twelve equivalent Fe(1) atoms to form AgFe12 cuboctahedra that share corners with twelve equivalent Ag(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Fe8Ag4 cuboctahedra, faces with six equivalent Ag(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Fe8Ag4 cuboctahedra.
