The crystal structure described by KCO3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 10-coordinate geometry to three equivalent O(2), three equivalent O(3), and four equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to four equivalent K(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent K(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent K(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
