The Materials Project

KC8 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. K1+ is bonded to twelve C+0.12- atoms to form edge-sharing KC12 cuboctahedra. There are eight shorter (3.04 Å) and four longer (3.06 Å) K–C bond lengths. There are two inequivalent C+0.12- sites. In the first C+0.12- site, C+0.12- is bonded in a distorted trigonal planar geometry to two equivalent K1+ and three C+0.12- atoms. There is two shorter (1.43 Å) and one longer (1.44 Å) C–C bond length. In the second C+0.12- site, C+0.12- is bonded in a distorted trigonal planar geometry to one K1+ and three C+0.12- atoms. The C–C bond length is 1.43 Å.
