The material described by LaKOCO3 crystallizes in the orthorhombic Pmmn space group. K(1) is bonded in a 9-coordinate geometry to four equivalent O(3) and five equivalent O(1) atoms. La(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to five equivalent K(1) and one C(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent La(1), and one C(1) atom. is represented by the CIF file [CIF]
