Na2ThF6 crystallizes in the trigonal P321 space group. Na(1) is bonded in a 6-coordinate geometry to three equivalent F(1) and three 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 Na(1) and two equivalent Th(1) atoms to form a mixture of distorted edge and corner-sharing FNa2Th2 tetrahedra. In the second F site, F(2) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Th(1) atom.
