SrThF6 crystallizes in the hexagonal P-6m2 space group. Sr(1) is bonded in a 11-coordinate geometry to two equivalent F(3), three equivalent F(1), and six equivalent F(4) atoms. Th(1) is bonded in a 11-coordinate geometry to two equivalent F(4), three equivalent F(2), and six equivalent F(3) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to three equivalent Sr(1) atoms. In the second F site, F(2) is bonded in a trigonal planar geometry to three equivalent Th(1) atoms. In the third F site, F(3) is bonded to one Sr(1) and three equivalent Th(1) atoms to form a mixture of distorted corner and face-sharing FSrTh3 tetrahedra. In the fourth F site, F(4) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one Th(1) atom.
