The compound described by Dy5Sn11 is Zirconium Disilicide-like structured and crystallizes in the monoclinic C2/m 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(2), four equivalent Sn(3), and four equivalent Sn(4) atoms. In the second Dy site, Dy(2) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(4), two equivalent Sn(5), and four equivalent Sn(2) atoms. In the third Dy site, Dy(3) is bonded to four equivalent Sn(1), four equivalent Sn(5), and four equivalent Sn(6) atoms to form a mixture of corner and face-sharing DySn12 cuboctahedra. There are six inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Dy(2), two equivalent Dy(3), two equivalent Sn(6), and four equivalent Sn(5) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), and two equivalent Sn(4) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Sn(3) atoms. In the fourth Sn site, Sn(4) is bonded in a 8-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), and two equivalent Sn(2) 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(6), and four equivalent Sn(1) atoms. In the sixth Sn site, Sn(6) is bonded in a square co-planar geometry to four equivalent Dy(3), four equivalent Sn(1), and four equivalent Sn(5) atoms. is represented by the CIF card [CIF]
