The material structure described by Dy5Sn13 crystallizes in the orthorhombic Immm space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(2) atoms. In the second Dy site, Dy(2) is bonded in a 10-coordinate geometry to two equivalent Sn(2), two equivalent Sn(5), two equivalent Sn(6), and four equivalent Sn(3) atoms. In the third Dy site, Dy(3) is bonded to four equivalent Sn(5), four equivalent Sn(6), and four equivalent Sn(7) atoms to form a mixture of face and corner-sharing DySn12 cuboctahedra. There are seven inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 7-coordinate geometry to two equivalent Dy(1) and five equivalent Sn(4) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), and two equivalent Sn(3) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), and two equivalent Sn(2) atoms. In the fourth Sn site, Sn(4) is bonded in a 7-coordinate geometry to two equivalent Dy(1) and five equivalent Sn(1) atoms. In the fifth Sn site, Sn(5) is bonded in a 10-coordinate geometry to two equivalent Dy(2), two equivalent Dy(3), two equivalent Sn(7), and four equivalent Sn(6) atoms. In the sixth Sn site, Sn(6) is bonded in a 10-coordinate geometry to two equivalent Dy(2), two equivalent Dy(3), two equivalent Sn(7), and four equivalent Sn(5) atoms. In the seventh Sn site, Sn(7) is bonded in a square co-planar geometry to four equivalent Dy(3), four equivalent Sn(5), and four equivalent Sn(6) atoms. is represented by the CIF file [CIF]
