The structure described by Tm5Re2C7 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded to two equivalent C(3) and four equivalent C(1) atoms to form TmC6 octahedra that share corners with four equivalent Re(1)C4 tetrahedra, edges with two equivalent Tm(1)C6 octahedra, edges with eight equivalent Tm(2)C5 square pyramids, and edges with two equivalent Re(1)C4 tetrahedra. In the second Tm site, Tm(2) is bonded to one C(1), two equivalent C(3), and two equivalent C(4) atoms to form distorted TmC5 square pyramids that share corners with five equivalent Tm(2)C5 square pyramids, corners with two equivalent Re(1)C4 tetrahedra, edges with two equivalent Tm(1)C6 octahedra, edges with four equivalent Tm(2)C5 square pyramids, and edges with two equivalent Re(1)C4 tetrahedra. Re(1) is bonded to two equivalent C(1) and two equivalent C(4) atoms to form distorted ReC4 tetrahedra that share corners with two equivalent Tm(1)C6 octahedra, corners with four equivalent Tm(2)C5 square pyramids, corners with four equivalent Re(1)C4 tetrahedra,  an edgeedge with one Tm(1)C6 octahedra, and edges with four equivalent Tm(2)C5 square pyramids. The corner-sharing octahedral tilt angles are 9°. There are four inequivalent C sites. In the first C site, C(1) is bonded to two equivalent Tm(1), two equivalent Tm(2), and two equivalent Re(1) atoms to form CTm4Re2 octahedra that share corners with two equivalent C(1)Tm4Re2 octahedra, edges with three equivalent C(1)Tm4Re2 octahedra, edges with four equivalent C(4)Tm4Re2 octahedra, and edges with four equivalent C(3)Tm5C octahedra. The corner-sharing octahedra are not tilted. In the second C site, C(2) is bonded in a linear geometry to two equivalent C(3) atoms. In the third C site, C(3) is bonded to one Tm(1), four equivalent Tm(2), and one C(2) atom to form CTm5C octahedra that share corners with two equivalent C(3)Tm5C octahedra, corners with four equivalent C(4)Tm4Re2 octahedra, edges with two equivalent C(4)Tm4Re2 octahedra, edges with two equivalent C(3)Tm5C octahedra, and edges with four equivalent C(1)Tm4Re2 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the fourth C site, C(4) is bonded to four equivalent Tm(2) and two equivalent Re(1) atoms to form CTm4Re2 octahedra that share corners with two equivalent C(4)Tm4Re2 octahedra, corners with four equivalent C(3)Tm5C octahedra, edges with two equivalent C(4)Tm4Re2 octahedra, edges with two equivalent C(3)Tm5C octahedra, and edges with four equivalent C(1)Tm4Re2 octahedra. The corner-sharing octahedral tilt angles range from 3-28°. is represented by the CIF file [CIF]
