The material structure described by Dy3(CuSi)4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 12-coordinate geometry to three equivalent Cu(1), three equivalent Cu(2), two equivalent Si(2), and four equivalent Si(1) atoms. In the second Dy site, Dy(2) is bonded to two equivalent Si(2) and four equivalent Si(1) atoms to form distorted edge-sharing DySi6 octahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to three equivalent Dy(1), one Cu(2), one Si(1), and three equivalent Si(2) atoms. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to three equivalent Dy(1), one Cu(1), one Si(1), and three equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), one Cu(1), one Cu(2), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to one Dy(2), two equivalent Dy(1), three equivalent Cu(1), and three equivalent Cu(2) atoms. is represented by the CIF file [CIF]
