CsY is alpha Samarium-derived structured and crystallizes in the hexagonal P-6m2 space group. Cs(1) is bonded to six equivalent Cs(1) and six equivalent Y(1) atoms to form CsCs6Y6 cuboctahedra that share corners with eighteen equivalent Cs(1)Cs6Y6 cuboctahedra, edges with six equivalent Cs(1)Cs6Y6 cuboctahedra, edges with twelve equivalent Y(1)Cs6Y6 cuboctahedra, faces with eight equivalent Cs(1)Cs6Y6 cuboctahedra, and faces with twelve equivalent Y(1)Cs6Y6 cuboctahedra. Y(1) is bonded to six equivalent Cs(1) and six equivalent Y(1) atoms to form YCs6Y6 cuboctahedra that share corners with eighteen equivalent Y(1)Cs6Y6 cuboctahedra, edges with six equivalent Y(1)Cs6Y6 cuboctahedra, edges with twelve equivalent Cs(1)Cs6Y6 cuboctahedra, faces with eight equivalent Y(1)Cs6Y6 cuboctahedra, and faces with twelve equivalent Cs(1)Cs6Y6 cuboctahedra.
