The material structure described by Dy3Cu4Sn4 crystallizes in the triclinic P-1 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form distorted edge-sharing DySn6 octahedra. In the second Dy site, Dy(2) is bonded in a 12-coordinate geometry to three equivalent Cu(1), three equivalent Cu(2), two equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to three equivalent Dy(2), one Cu(2), one Sn(2), and three equivalent Sn(1) atoms. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to three equivalent Dy(2), one Cu(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to one Dy(1), two equivalent Dy(2), three equivalent Cu(1), and three equivalent Cu(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), one Cu(1), one Cu(2), and one Sn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
