The structure described by KC2 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 9-coordinate geometry to four equivalent C(1) and five equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one C(1) atom. In the second C site, C(2) is bonded in a 4-coordinate geometry to five equivalent K(1) and one C(2) atom. is represented by the CIF file [CIF]
