The structure described by Tm5B2(O2F3)3 crystallizes in the monoclinic C2/c space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 9-coordinate geometry to one O(1), one O(3), two equivalent O(2), one F(2), two equivalent F(1), and two equivalent F(4) atoms. In the second Tm site, Tm(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one F(1), one F(3), one F(5), and two equivalent F(2) atoms. In the third Tm site, Tm(3) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), one F(3), and four equivalent F(5) atoms. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to one Tm(2), two equivalent Tm(1), and one B(1) atom. In the second O site, O(3) is bonded in a distorted single-bond geometry to one Tm(1), one Tm(2), one Tm(3), and one B(1) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one Tm(1), one Tm(2), one Tm(3), and one B(1) atom. There are five inequivalent F sites. In the first F site, F(5) is bonded in a 3-coordinate geometry to one Tm(2) and two equivalent Tm(3) atoms. In the second F site, F(3) is bonded in a 3-coordinate geometry to one Tm(3) and two equivalent Tm(2) atoms. In the third F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to one Tm(2) and two equivalent Tm(1) atoms. In the fourth F site, F(2) is bonded in a distorted trigonal non-coplanar geometry to one Tm(1) and two equivalent Tm(2) atoms. In the fifth F site, F(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Tm(1) atoms. is represented by the CIF file [CIF]
