The structure described by Dy2NiSn6 crystallizes in the orthorhombic Cmmm space group. Dy(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(3), and six equivalent Sn(2) atoms. Ni(1) is bonded in a body-centered cubic geometry to four equivalent Sn(1) and four equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Dy(1), two equivalent Ni(1), one Sn(1), and four equivalent Sn(3) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to six equivalent Dy(1) and two equivalent Sn(2) atoms. In the third Sn site, Sn(3) is bonded in a 4-coordinate geometry to two equivalent Dy(1), two equivalent Ni(1), and four equivalent Sn(1) atoms. is represented by the CIF card [CIF]
