KCe(OCl)4 crystallizes in the orthorhombic P2_12_12 space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent Cl(1), and four equivalent Cl(2) atoms. Ce(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent Cl(1), and two equivalent Cl(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one Cl(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Ce(1), and one Cl(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to two equivalent K(1), one Ce(1), and one O(2) atom to form a mixture of distorted corner and edge-sharing ClK2CeO tetrahedra. In the second Cl site, Cl(2) is bonded to two equivalent K(1), one Ce(1), and one O(1) atom to form a mixture of distorted corner and edge-sharing ClK2CeO tetrahedra.
