PtW is alpha La-derived structured and crystallizes in the trigonal R-3m space group. W(1) is bonded to six equivalent W(1) and six equivalent Pt(1) atoms to form WPt6W6 cuboctahedra that share corners with twelve equivalent W(1)Pt6W6 cuboctahedra, edges with twelve equivalent W(1)Pt6W6 cuboctahedra, edges with twelve equivalent Pt(1)Pt6W6 cuboctahedra, faces with six equivalent W(1)Pt6W6 cuboctahedra, and faces with twelve equivalent Pt(1)Pt6W6 cuboctahedra. Pt(1) is bonded to six equivalent W(1) and six equivalent Pt(1) atoms to form PtPt6W6 cuboctahedra that share corners with twelve equivalent Pt(1)Pt6W6 cuboctahedra, edges with twelve equivalent W(1)Pt6W6 cuboctahedra, edges with twelve equivalent Pt(1)Pt6W6 cuboctahedra, faces with six equivalent Pt(1)Pt6W6 cuboctahedra, and faces with twelve equivalent W(1)Pt6W6 cuboctahedra.
