Tm11Ge10 is delta Molybdenum Boride-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are four inequivalent Tm sites. In the first Tm site, Tm is bonded to seven Ge atoms to form a mixture of distorted corner, edge, and face-sharing TmGe7 pentagonal bipyramids. There are a spread of Tm–Ge bond distances ranging from 2.85–3.29 Å. In the second Tm site, Tm is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Tm–Ge bond distances ranging from 2.76–3.40 Å. In the third Tm site, Tm is bonded in a 9-coordinate geometry to nine Ge atoms. There are a spread of Tm–Ge bond distances ranging from 3.19–3.64 Å. In the fourth Tm site, Tm is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Tm–Ge bond distances ranging from 2.87–3.05 Å. There are five inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to eight Tm atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to nine Tm atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to seven Tm and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.62 Å. In the fourth Ge site, Ge is bonded in a 8-coordinate geometry to eight Tm atoms. In the fifth Ge site, Ge is bonded in a 9-coordinate geometry to eight Tm and one Ge atom. The Ge–Ge bond length is 2.56 Å.
