The crystal structure described by K4CO4 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. C(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to six equivalent K(1) and one C(1) atom. is represented by the CIF file [CIF]
