Materials Data on Dy2Tl by Materials Project
Dy2Tl crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 6-coordinate geometry to eight Dy and six equivalent Tl atoms. There are two shorter (3.37 Å) and six longer (3.55 Å) Dy–Dy bond lengths. All Dy–Tl bond lengths are 3.55 Å. In the second Dy site, Dy is bonded to six equivalent Dy and five equivalent Tl atoms to form a mixture of distorted corner and face-sharing DyDy6Tl5 trigonal bipyramids. There are three shorter (3.13 Å) and two longer (3.37 Å) Dy–Tl bond lengths. Tl is bonded in a 11-coordinate geometry to eleven Dy atoms.
