Materials Data on Pr2Tl by Materials Project
Pr2Tl crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 6-coordinate geometry to eight Pr and six equivalent Tl atoms. There are two shorter (3.50 Å) and six longer (3.69 Å) Pr–Pr bond lengths. All Pr–Tl bond lengths are 3.69 Å. In the second Pr site, Pr is bonded to six equivalent Pr and five equivalent Tl atoms to form a mixture of distorted corner and face-sharing PrPr6Tl5 trigonal bipyramids. There are three shorter (3.25 Å) and two longer (3.50 Å) Pr–Tl bond lengths. Tl is bonded in a 11-coordinate geometry to eleven Pr atoms.
