The crystal structure described by Tm2OsB6 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 17-coordinate geometry to three equivalent Os(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), two equivalent B(6), and four equivalent B(1) atoms. In the second Tm site, Tm(2) is bonded in a 14-coordinate geometry to two equivalent Os(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), and four equivalent B(6) atoms. Os(1) is bonded in a 15-coordinate geometry to two equivalent Tm(2), three equivalent Tm(1), two equivalent B(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), and two equivalent B(5) atoms. There are six inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent Tm(1), two equivalent Os(1), one B(1), one B(2), and one B(5) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), two equivalent Os(1), one B(1), one B(3), and one B(6) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), two equivalent Os(1), one B(2), one B(4), and one B(5) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), two equivalent Os(1), one B(3), one B(5), and one B(6) atom. In the fifth B site, B(5) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), two equivalent Os(1), one B(1), one B(3), and one B(4) atom. In the sixth B site, B(6) is bonded in a 9-coordinate geometry to two equivalent Tm(1), four equivalent Tm(2), one B(2), one B(4), and one B(6) atom. is represented by the CIF card [CIF]
