Materials Data on K4CO6 by Materials Project
K4CO6 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a 5-coordinate geometry to five O atoms. There are a spread of K–O bond distances ranging from 2.69–3.00 Å. In the second K site, K is bonded in a distorted square pyramidal geometry to five O atoms. There are a spread of K–O bond distances ranging from 2.55–2.93 Å. In the third K site, K is bonded in a 6-coordinate geometry to six O atoms. There are a spread of K–O bond distances ranging from 2.59–3.10 Å. In the fourth K site, K is bonded in a 5-coordinate geometry to five O atoms. There are a spread of K–O bond distances ranging from 2.65–2.78 Å. C is bonded in a trigonal planar geometry to three O atoms. There are a spread of C–O bond distances ranging from 1.29–1.32 Å. There are six inequivalent O sites. In the first O site, O is bonded in a distorted rectangular see-saw-like geometry to three K and one C atom. In the second O site, O is bonded in a 4-coordinate geometry to three K and one O atom. The O–O bond length is 1.34 Å. In the third O site, O is bonded in a rectangular see-saw-like geometry to four K atoms. In the fourth O site, O is bonded in a distorted single-bond geometry to four K and one C atom. In the fifth O site, O is bonded in a distorted single-bond geometry to three K and one C atom. In the sixth O site, O is bonded to four K and one O atom to form corner-sharing OK4O square pyramids.
