DySn3 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent Sn(1), two equivalent Sn(3), two equivalent Sn(5), two equivalent Sn(6), and four equivalent Sn(4) atoms to form DySn12 cuboctahedra that share corners with four equivalent Dy(1)Sn12 cuboctahedra, corners with two equivalent Sn(2)Dy4Sn square pyramids, and faces with four equivalent Dy(1)Sn12 cuboctahedra. In the second Dy site, Dy(2) is bonded in a 9-coordinate geometry to one Sn(5), two equivalent Sn(1), two equivalent Sn(6), and four equivalent Sn(2) atoms. There are six inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), and four equivalent Sn(6) atoms.

In the third Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Dy(1), one Sn(2), two equivalent Sn(4), and four equivalent Sn(5) atoms. In the fourth Sn site, Sn(4) is bonded in a rectangular see-saw-like geometry to four equivalent Dy(1), two equivalent Sn(3), and two equivalent Sn(5) atoms.
