The Materials Project

K2CO3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a hexagonal planar geometry to six equivalent O2- atoms. All K–O bond lengths are 2.92 Å. In the second K1+ site, K1+ is bonded to six equivalent O2- atoms to form face-sharing KO6 octahedra. All K–O bond lengths are 2.71 Å. C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. O2- is bonded in a distorted single-bond geometry to four K1+ and one C4+ atom.
