The structure described by Sc5Re2C7 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to one C(4), two equivalent C(2), and two equivalent C(3) atoms to form ScC5 square pyramids that share corners with five equivalent Sc(1)C5 square pyramids, corners with two equivalent Re(1)C4 trigonal pyramids, edges with two equivalent Sc(2)C6 octahedra, edges with four equivalent Sc(1)C5 square pyramids, and edges with two equivalent Re(1)C4 trigonal pyramids. In the second Sc site, Sc(2) is bonded to two equivalent C(3) and four equivalent C(4) atoms to form ScC6 octahedra that share corners with four equivalent Re(1)C4 trigonal pyramids, edges with two equivalent Sc(2)C6 octahedra, edges with eight equivalent Sc(1)C5 square pyramids, and edges with two equivalent Re(1)C4 trigonal pyramids. Re(1) is bonded to two equivalent C(2) and two equivalent C(4) atoms to form distorted ReC4 trigonal pyramids that share corners with two equivalent Sc(2)C6 octahedra, corners with four equivalent Sc(1)C5 square pyramids, corners with four equivalent Re(1)C4 trigonal pyramids,  an edgeedge with one Sc(2)C6 octahedra, and edges with four equivalent Sc(1)C5 square pyramids. The corner-sharing octahedral tilt angles are 6°. There are four inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to two equivalent C(3) atoms. In the second C site, C(2) is bonded to four equivalent Sc(1) and two equivalent Re(1) atoms to form CSc4Re2 octahedra that share corners with two equivalent C(2)Sc4Re2 octahedra, corners with four equivalent C(3)Sc5C octahedra, edges with two equivalent C(2)Sc4Re2 octahedra, edges with two equivalent C(3)Sc5C octahedra, and edges with four equivalent C(4)Sc4Re2 octahedra. The corner-sharing octahedral tilt angles range from 2-28°. In the third C site, C(3) is bonded to one Sc(2), four equivalent Sc(1), and one C(1) atom to form CSc5C octahedra that share corners with two equivalent C(3)Sc5C octahedra, corners with four equivalent C(2)Sc4Re2 octahedra, edges with two equivalent C(2)Sc4Re2 octahedra, edges with two equivalent C(3)Sc5C octahedra, and edges with four equivalent C(4)Sc4Re2 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. In the fourth C site, C(4) is bonded to two equivalent Sc(1), two equivalent Sc(2), and two equivalent Re(1) atoms to form CSc4Re2 octahedra that share corners with two equivalent C(4)Sc4Re2 octahedra, edges with three equivalent C(4)Sc4Re2 octahedra, edges with four equivalent C(2)Sc4Re2 octahedra, and edges with four equivalent C(3)Sc5C octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
