KTh6F25 crystallizes in the trigonal R-3m space group. K(1) is bonded in a cuboctahedral geometry to six equivalent F(1) and six equivalent F(4) atoms. Th(1) is bonded in a 9-coordinate geometry to one F(2), one F(3), one F(6), two equivalent F(1), two equivalent F(4), and two equivalent F(5) atoms. There are six inequivalent F sites. In the first F site, F(5) is bonded in a bent 150 degrees geometry to two equivalent Th(1) atoms. In the second F site, F(6) is bonded in a trigonal non-coplanar geometry to three equivalent Th(1) atoms. In the third F site, F(1) is bonded in a distorted trigonal planar geometry to one K(1) and two equivalent Th(1) atoms. In the fourth F site, F(2) is bonded in a trigonal non-coplanar geometry to three equivalent Th(1) atoms. In the fifth F site, F(3) is bonded in a linear geometry to two equivalent Th(1) atoms. In the sixth F site, F(4) is bonded in a distorted bent 120 degrees geometry to one K(1) and two equivalent Th(1) atoms.
