The compound described by K4CO4 crystallizes in the tetragonal I-4 space group. K(1) is bonded in a 5-coordinate geometry to five 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 five equivalent K(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
