The material described by K2ThF6 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. Th(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 Th(1) atoms to form a mixture of corner and edge-sharing FK2Th2 tetrahedra. In the second F site, F(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Th(1) atom. is represented by the CIF file [CIF]
