The compound described by Dy2Tl crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 14-coordinate geometry to two equivalent Dy(1), six equivalent Dy(2), and six equivalent Tl(1) atoms. In the second Dy site, Dy(2) is bonded to six equivalent Dy(1) and five equivalent Tl(1) atoms to form a mixture of distorted corner and face-sharing DyDy6Tl5 trigonal bipyramids. Tl(1) is bonded in a 11-coordinate geometry to five equivalent Dy(2) and six equivalent Dy(1) atoms. is represented by the CIF file [CIF]
