The crystal structure described by Dy5Sn4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to one Sn(3), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the second Dy site, Dy(2) is bonded in a 7-coordinate geometry to one Sn(2), two equivalent Sn(3), and four equivalent Sn(1) atoms. In the third Dy site, Dy(3) is bonded to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms to form corner-sharing DySn6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. There are three inequivalent Sn sites. In the first Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Dy(1), two equivalent Dy(3), four equivalent Dy(2), and one Sn(2) atom. In the second Sn site, Sn(1) is bonded in a 8-coordinate geometry to one Dy(3), three equivalent Dy(1), and four equivalent Dy(2) atoms. In the third Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Dy(2), two equivalent Dy(3), four equivalent Dy(1), and one Sn(3) atom. is represented by the CIF file [CIF]
