Tm5Rh4Ge10 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 14-coordinate geometry to four equivalent Rh(1), two equivalent Ge(1), four equivalent Ge(2), and four equivalent Ge(3) atoms. In the second Tm site, Tm(2) is bonded to four equivalent Rh(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form face-sharing TmGe8Rh4 cuboctahedra. In the third Tm site, Tm(3) is bonded in a 16-coordinate geometry to four equivalent Rh(1), four equivalent Ge(2), and eight equivalent Ge(1) atoms. Rh(1) is bonded in a 10-coordinate geometry to one Tm(3), two equivalent Tm(1), two equivalent Tm(2), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Tm(1), one Tm(2), two equivalent Tm(3), and two equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to one Tm(3), two equivalent Tm(1), two equivalent Tm(2), and two equivalent Rh(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Tm(2), four equivalent Tm(1), two equivalent Rh(1), and one Ge(3) atom.
