The material structure described by KY is alpha Samarium-derived structured and crystallizes in the hexagonal P-6m2 space group. K(1) is bonded to six equivalent K(1) and six equivalent Y(1) atoms to form KK6Y6 cuboctahedra that share corners with eighteen equivalent K(1)K6Y6 cuboctahedra, edges with six equivalent K(1)K6Y6 cuboctahedra, edges with twelve equivalent Y(1)K6Y6 cuboctahedra, faces with eight equivalent K(1)K6Y6 cuboctahedra, and faces with twelve equivalent Y(1)K6Y6 cuboctahedra.
