The structure described by CsC8 crystallizes in the hexagonal P6/mmm space group. Cs(1) is bonded to twelve C(1,1,1,1,1) atoms to form face-sharing CsC12 cuboctahedra. There are six inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1); one C(2); and two C(1,1) atoms. In the second C site, C(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1); one C(2); and two C(1,1) atoms. In the third C site, C(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1); one C(2); and two C(1,1) atoms. In the fourth C site, C(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1); one C(2); and two C(1,1) atoms. In the fifth C site, C(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1); one C(2); and two C(1,1) atoms. In the sixth C site, C(2) is bonded in a trigonal planar geometry to three C(1,1,1) atoms. is represented by the CIF file [CIF]
