The structure described by Dy4C5 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 9-coordinate geometry to one C(1), four equivalent C(2), and four equivalent C(3) atoms. In the second Dy site, Dy(2) is bonded to one C(2), two equivalent C(1), and two equivalent C(3) atoms to form DyC5 trigonal bipyramids that share corners with two equivalent C(2)Dy5C octahedra, corners with four equivalent Dy(2)C5 trigonal bipyramids, and edges with two equivalent Dy(2)C5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 35-48°. There are three inequivalent C sites. In the first C site, C(1) is bonded to two equivalent Dy(1) and four equivalent Dy(2) atoms to form CDy6 octahedra that share corners with four equivalent C(2)Dy5C octahedra, edges with two equivalent C(1)Dy6 octahedra, and edges with four equivalent C(2)Dy5C octahedra. The corner-sharing octahedral tilt angles are 61°. In the second C site, C(2) is bonded to one Dy(2), four equivalent Dy(1), and one C(3) atom to form CDy5C octahedra that share corners with two equivalent C(1)Dy6 octahedra, corners with four equivalent C(2)Dy5C octahedra, corners with two equivalent Dy(2)C5 trigonal bipyramids, edges with two equivalent C(1)Dy6 octahedra, and edges with four equivalent C(2)Dy5C octahedra. The corner-sharing octahedral tilt angles range from 29-61°. In the third C site, C(3) is bonded in a 7-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), and one C(2) atom. is represented by the CIF file [CIF]
