The material described by Dy2Sn5 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), four equivalent Sn(3), and four equivalent Sn(5) atoms. In the second Dy site, Dy(2) is bonded in a 10-coordinate geometry to two equivalent Sn(2), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(1) atoms. There are five inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), and two equivalent Sn(3) atoms. In the second Sn site, Sn(2) is bonded in a 7-coordinate geometry to two equivalent Dy(2) and five equivalent Sn(4) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), and two equivalent Sn(1) atoms. In the fourth Sn site, Sn(4) is bonded in a 7-coordinate geometry to two equivalent Dy(2) and five equivalent Sn(2) atoms. In the fifth Sn site, Sn(5) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Sn(5) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
