Materials Data on PrTlPd by Materials Project

Abstract

PrPdTl crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Pr is bonded in a 10-coordinate geometry to two equivalent Pr, five Pd, and three equivalent Tl atoms. Both Pr–Pr bond lengths are 3.24 Å. There are four shorter (3.32 Å) and one longer (3.48 Å) Pr–Pd bond lengths. There are one shorter (3.02 Å) and two longer (3.17 Å) Pr–Tl bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a distorted trigonal planar geometry to three equivalent Pr and three equivalent Tl atoms. All Pd–Tl bond lengths are 2.73 Å. In the second Pd site, Pd is bonded in a 6-coordinate geometry to six equivalent Pr atoms. Tl is bonded in a 6-coordinate geometry to three equivalent Pr and one Pd atom.
