Cs crystallizes in the cubic Pm-3n space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a distorted linear geometry to two equivalent Cs(1) and four equivalent Cs(2) atoms. In the second Cs site, Cs(2) is bonded to twelve equivalent Cs(1) atoms to form a mixture of face and edge-sharing CsCs12 cuboctahedra.
Cs crystallizes in the cubic Pm-3n space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a distorted linear geometry to two equivalent Cs(1) and four equivalent Cs(2) atoms. Both Cs(1)-Cs(1) bond lengths are 4.98 Å. All Cs(1)-Cs(2) bond lengths are 5.57 Å. In the second Cs site, Cs(2) is bonded to twelve equivalent Cs(1) atoms to form a mixture of face and edge-sharing CsCs12 cuboctahedra.
