The material structure described by Y8Rh5C12 crystallizes in the monoclinic C2/m space group. There are four inequivalent Y sites. In the first Y site, Y(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 Y site, Y(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 third Y site, Y(3) is bonded in a 8-coordinate geometry to two equivalent Rh(3), two equivalent C(1), two equivalent C(2), and two equivalent C(5) atoms. In the fourth Y site, Y(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 linear geometry to four equivalent Y(4) and two equivalent C(1) atoms. In the second Rh site, Rh(2) is bonded in a 2-coordinate geometry to two equivalent Y(2), two equivalent Y(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 Y(3), two equivalent Y(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 Y(1), three equivalent Y(2), and one C(3) atom to form a mixture of distorted corner and edge-sharing CY5C octahedra. The corner-sharing octahedral tilt angles range from 6-15°. In the second C site, C(5) is bonded in a 4-coordinate geometry to two equivalent Y(2), two equivalent Y(3), one Rh(3), and one C(6) atom. In the third C site, C(6) is bonded to two equivalent Y(2), three equivalent Y(1), and one C(5) atom to form a mixture of corner and edge-sharing CY5C octahedra. The corner-sharing octahedral tilt angles range from 6-15°. In the fourth C site, C(1) is bonded to two equivalent Y(3), two equivalent Y(4), one Rh(1), and one C(2) atom to form a mixture of corner and edge-sharing CY4RhC 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 Y(3), two equivalent Y(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 Y(1), two equivalent Y(2), one Rh(2), one Rh(3), and one C(4) atom. is represented by the CIF card [CIF]
