PtAg crystallizes in the hexagonal P-6m2 space group. Pt(1) is bonded to six equivalent Pt(1) and six equivalent Ag(1) atoms to form PtAg6Pt6 cuboctahedra that share corners with eighteen equivalent Pt(1)Ag6Pt6 cuboctahedra, edges with six equivalent Pt(1)Ag6Pt6 cuboctahedra, edges with twelve equivalent Ag(1)Ag6Pt6 cuboctahedra, faces with eight equivalent Pt(1)Ag6Pt6 cuboctahedra, and faces with twelve equivalent Ag(1)Ag6Pt6 cuboctahedra. Ag(1) is bonded to six equivalent Pt(1) and six equivalent Ag(1) atoms to form AgAg6Pt6 cuboctahedra that share corners with eighteen equivalent Ag(1)Ag6Pt6 cuboctahedra, edges with six equivalent Ag(1)Ag6Pt6 cuboctahedra, edges with twelve equivalent Pt(1)Ag6Pt6 cuboctahedra, faces with eight equivalent Ag(1)Ag6Pt6 cuboctahedra, and faces with twelve equivalent Pt(1)Ag6Pt6 cuboctahedra.
