LaKOCO3 crystallizes in the orthorhombic Pcca space group. K(1) is bonded to one C(1) and five equivalent O(1) atoms to form a mixture of corner and edge-sharing KCO5 octahedra. The corner-sharing octahedra are not tilted. La(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(2) and four equivalent O(3) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one K(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to five equivalent K(1) atoms to form a mixture of corner and edge-sharing OK5 square pyramids. In the second O site, O(2) is bonded in a distorted L-shaped geometry to one La(1) and one C(1) atom. In the third O site, O(3) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra.
LaKOCO3 crystallizes in the orthorhombic Pcca space group. K(1) is bonded to one C(1) and five equivalent O(1) atoms to form a mixture of corner and edge-sharing KCO5 octahedra. The corner-sharing octahedra are not tilted. The K(1)-C(1) bond length is 3.11 Å. There are a spread of K(1)-O(1) bond distances ranging from 2.55-2.98 Å. La(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(2) and four equivalent O(3) atoms. Both La(1)-O(2) bond lengths are 2.47 Å. There are two shorter (2.39 Å) and two longer (2.46 Å) La(1)-O(3) bond lengths. C(1) is bonded in a distorted bent 120 degrees geometry to one K(1) and two equivalent O(2) atoms. Both C(1)-O(2) bond lengths are 1.24 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded to five equivalent K(1) atoms to form a mixture of corner and edge-sharing OK5 square pyramids.
