K2CeF6 crystallizes in the hexagonal P-62m space group. K(1) is bonded in a 9-coordinate geometry to three equivalent F(1) and six equivalent F(2) atoms. Ce(1) is bonded in a 9-coordinate geometry to three equivalent F(2) and six equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded to two equivalent K(1) and two equivalent Ce(1) atoms to form a mixture of corner and edge-sharing FK2Ce2 tetrahedra. In the second F site, F(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Ce(1) atom.
