Materials Data on Tl9Pd13 by Materials Project

Pd13Tl9 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are four inequivalent Pd sites. In the first Pd site, Pd is bonded in a distorted linear geometry to six equivalent Pd and eight Tl atoms. All Pd–Pd bond lengths are 2.91 Å. There are two shorter (2.89 Å) and six longer (3.37 Å) Pd–Tl bond lengths. In the second Pd site, Pd is bonded in a 12-coordinate geometry to six Tl atoms. There are four shorter (2.85 Å) and two longer (3.02 Å) Pd–Tl bond lengths. In the third Pd site, Pd is bonded in a 12-coordinate geometry to six Tl atoms. There are four shorter (2.87 Å) and two longer (3.01 Å) Pd–Tl bond lengths. In the fourth Pd site, Pd is bonded in a 6-coordinate geometry to one Pd and six Tl atoms. There are a spread of Pd–Tl bond distances ranging from 2.76–2.97 Å. There are three inequivalent Tl sites. In the first Tl site, Tl is bonded in a distorted body-centered cubic geometry to eight Pd atoms. In the second Tl site, Tl is bonded in a 9-coordinate geometry to nine Pd atoms. In the third Tl site, Tl is bonded in a 8-coordinate geometry to nine Pd atoms.
