The material described by Dy3Ag4Sn4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to eight equivalent Ag(1), two equivalent Sn(1), and four equivalent Sn(2) atoms to form distorted face-sharing DyAg8Sn6 octahedra. In the second Dy site, Dy(2) is bonded in a 12-coordinate geometry to six equivalent Ag(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. Ag(1) is bonded in a 12-coordinate geometry to two equivalent Dy(1), three equivalent Dy(2), three equivalent Ag(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), and six equivalent Ag(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), two equivalent Ag(1), and one Sn(2) atom. is represented by the CIF file [CIF]
