The crystal structure described by KC2 crystallizes in the orthorhombic Immm space group. K(1) is bonded to eight equivalent C(1) atoms to form KC8 hexagonal bipyramids that share corners with eight equivalent C(1)K4C trigonal bipyramids and edges with twelve equivalent K(1)C8 hexagonal bipyramids. C(1) is bonded to four equivalent K(1) and one C(1) atom to form distorted CK4C trigonal bipyramids that share corners with four equivalent K(1)C8 hexagonal bipyramids, corners with sixteen equivalent C(1)K4C trigonal bipyramids, and edges with six equivalent C(1)K4C trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
