TmOsB4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Tm3+ is bonded in a 2-coordinate geometry to fourteen B+1.50- atoms. There are a spread of Tm–B bond distances ranging from 2.62–2.76 Å. Os3+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Os–B bond distances ranging from 2.25–2.41 Å. There are four inequivalent B+1.50- sites. In the first B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Os3+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.75–1.87 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Os3+, and three B+1.50- atoms. The B–B bond length is 1.85 Å. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Os3+, and three B+1.50- atoms. There is one shorter (1.74 Å) and one longer (1.75 Å) B–B bond length. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent Tm3+, four equivalent Os3+, and three B+1.50- atoms. The B–B bond length is 1.72 Å.
