Cs crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Cs cluster. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a distorted single-bond geometry to one Cs(2) atom. The Cs(1)-Cs(2) bond length is 1.91 Å. In the second Cs site, Cs(2) is bonded in a distorted bent 150 degrees geometry to one Cs(1) and one Cs(2) atom. The Cs(2)-Cs(2) bond length is 3.22 Å.
