Cs is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to six equivalent Cs(1) and six equivalent Cs(2) atoms to form a mixture of distorted face, corner, and edge-sharing CsCs12 cuboctahedra. In the second Cs site, Cs(2) is bonded to six equivalent Cs(1) and six equivalent Cs(2) atoms to form a mixture of distorted face, corner, and edge-sharing CsCs12 cuboctahedra.

In the first Cs site, Cs(1) is bonded to six equivalent Cs(1) and six equivalent Cs(2) atoms to form a mixture of distorted face, corner, and edge-sharing CsCs12 cuboctahedra. All Cs(1)-Cs(1) bond lengths are 5.57 Å. All Cs(1)-Cs(2) bond lengths are 5.64 Å. In the second Cs site, Cs(2) is bonded to six equivalent Cs(1) and six equivalent Cs(2) atoms to form a mixture of distorted face, corner, and edge-sharing CsCs12 cuboctahedra. All Cs(2)-Cs(2) bond lengths are 5.57 Å.
