The material structure described by PtK crystallizes in the hexagonal P-6m2 space group. K(1) is bonded to six equivalent K(1) and six equivalent Pt(1) atoms to form distorted KK6Pt6 cuboctahedra that share corners with eighteen equivalent K(1)K6Pt6 cuboctahedra, edges with six equivalent K(1)K6Pt6 cuboctahedra, edges with twelve equivalent Pt(1)K6Pt6 cuboctahedra, faces with eight equivalent K(1)K6Pt6 cuboctahedra, and faces with twelve equivalent Pt(1)K6Pt6 cuboctahedra.
