TmCoB4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Tm3+ is bonded in a 4-coordinate geometry to fourteen B+1.50- atoms. There are a spread of Tm–B bond distances ranging from 2.55–2.69 Å. Co3+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Co–B bond distances ranging from 2.18–2.28 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 two equivalent Tm3+, four equivalent Co3+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.68–1.73 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Co3+, and three B+1.50- atoms. There is one shorter (1.78 Å) and one longer (1.80 Å) B–B bond length. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Co3+, and three B+1.50- atoms. Both B–B bond lengths are 1.80 Å. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Tm3+, two equivalent Co3+, and three B+1.50- atoms.
