CCs crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to two equivalent C(2) and three equivalent C(1) atoms to form distorted edge-sharing CsC5 square pyramids. In the second Cs site, Cs(2) is bonded in a 7-coordinate geometry to three equivalent C(1) and four equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to three equivalent Cs(1), three equivalent Cs(2), and one C(2) atom. In the second C site, C(2) is bonded in a 7-coordinate geometry to two equivalent Cs(1), four equivalent Cs(2), and one C(1) atom.

In the first Cs site, Cs(1) is bonded to two equivalent C(2) and three equivalent C(1) atoms to form distorted edge-sharing CsC5 square pyramids. Both Cs(1)-C(2) bond lengths are 3.53 Å. There is one shorter (3.33 Å) and two longer (3.45 Å) Cs(1)-C(1) bond lengths. In the second Cs site, Cs(2) is bonded in a 7-coordinate geometry to three equivalent C(1) and four equivalent C(2) atoms. There are two shorter (3.31 Å) and one longer (3.59 Å) Cs(2)-C(1) bond length. There are a spread of Cs(2)-C(2) bond distances ranging from 3.34-3.44 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to three equivalent Cs(1), three equivalent Cs(2), and one C(2) atom. The C(1)-C(2) bond length is 1.27 Å. In the second C site, C(2) is bonded in a 7-coordinate geometry to two equivalent Cs(1), four equivalent Cs(2), and one C(1) atom.
