The compound described by K4CO6 crystallizes in the triclinic P1 space group. There are four inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(3), and two equivalent O(6) atoms. In the second K site, K(2) is bonded in a distorted square pyramidal geometry to one O(1), one O(3), one O(4), one O(5), and one O(6) atom. In the third K site, K(3) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the fourth K site, K(4) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(5), and two equivalent O(4) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one K(2), one K(3), one K(4), and one C(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one K(3), one K(4), and one O(6) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one K(2), one K(3), and two equivalent K(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(2), one K(3), two equivalent K(4), and one C(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one K(2), one K(3), one K(4), and one C(1) atom. In the sixth O site, O(6) is bonded to one K(2), one K(3), two equivalent K(1), and one O(2) atom to form corner-sharing OK4O square pyramids. is represented by the CIF file [CIF]
