The crystal structure described by Tm8Rh5C12 crystallizes in the monoclinic C2/m space group. There are four inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 5-coordinate geometry to two equivalent C(3), two equivalent C(4), and three equivalent C(6) atoms. In the second Tm site, Tm(2) is bonded in a 11-coordinate geometry to two equivalent Rh(2), two equivalent C(3), two equivalent C(5), two equivalent C(6), and three equivalent C(4) atoms.

In the fourth Tm site, Tm(4) is bonded in a 10-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Rh(3), two equivalent C(1), and two equivalent C(2) atoms. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted linear geometry to four equivalent Tm(4) and two equivalent C(1) atoms. In the second Rh site, Rh(2) is bonded in a 2-coordinate geometry to two equivalent Tm(2), two equivalent Tm(4), one C(2), and one C(3) atom. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to two equivalent Tm(3), two equivalent Tm(4), one C(3), and one C(5) atom. There are six inequivalent C sites. In the first C site, C(4) is bonded to two equivalent Tm(1), three equivalent Tm(2), and one C(3) atom to form a mixture of distorted edge and corner-sharing CTm5C octahedra. The corner-sharing octahedral tilt angles range from 7-15°. In the second C site, C(5) is bonded in a 4-coordinate geometry to two equivalent Tm(2), two equivalent Tm(3), one Rh(3), and one C(6) atom. In the third C site, C(6) is bonded to two equivalent Tm(2), three equivalent Tm(1), and one C(5) atom to form a mixture of edge and corner-sharing CTm5C octahedra. The corner-sharing octahedral tilt angles range from 7-15°. In the fourth C site, C(1) is bonded to two equivalent Tm(3), two equivalent Tm(4), one Rh(1), and one C(2) atom to form a mixture of edge and corner-sharing CTm4RhC octahedra. The corner-sharing octahedra are not tilted. In the fifth C site, C(2) is bonded in a 6-coordinate geometry to two equivalent Tm(3), two equivalent Tm(4), one Rh(2), and one C(1) atom. In the sixth C site, C(3) is bonded in a 7-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), one Rh(2), one Rh(3), and one C(4) atom. is represented by the CIF card [CIF]
