Materials Data on Sb3Pd8 by Materials Project

Abstract

Pd8Sb3 crystallizes in the trigonal R3c space group. The structure is three-dimensional. there are eight inequivalent Pd sites. In the first Pd site, Pd is bonded in a 3-coordinate geometry to five Pd and three Sb atoms. There are a spread of Pd–Pd bond distances ranging from 2.90–3.32 Å. There are a spread of Pd–Sb bond distances ranging from 2.70–2.80 Å. In the second Pd site, Pd is bonded in a 4-coordinate geometry to three equivalent Pd and four Sb atoms. All Pd–Pd bond lengths are 3.20 Å. There are one shorter (2.69 Å) and three longer (2.80 Å) Pd–Sb bond lengths. In the third Pd site, Pd is bonded in a 11-coordinate geometry to seven Pd and four Sb atoms. There are one shorter (2.77 Å) and three longer (2.86 Å) Pd–Pd bond lengths. There are one shorter (2.71 Å) and three longer (2.81 Å) Pd–Sb bond lengths. In the fourth Pd site, Pd is bonded in a 3-coordinate geometry to five Pd and three Sb atoms. There are a spread of Pd–Pd bond distances ranging from 2.89–3.29 Å. There are a spread of Pd–Sb bond distances ranging from 2.70–2.82 Å. In the fifth Pd site, Pd is bonded in a 4-coordinate geometry to three equivalent Pd and four Sb atoms. All Pd–Pd bond lengths are 3.14 Å. There are one shorter (2.70 Å) and three longer (2.82 Å) Pd–Sb bond lengths. In the sixth Pd site, Pd is bonded in a 11-coordinate geometry to seven Pd and four Sb atoms. All Pd–Pd bond lengths are 2.87 Å. There are one shorter (2.66 Å) and three longer (2.81 Å) Pd–Sb bond lengths. In the seventh Pd site, Pd is bonded in a 4-coordinate geometry to nine Pd and four Sb atoms. There are a spread of Pd–Pd bond distances ranging from 2.93–3.12 Å. There are a spread of Pd–Sb bond distances ranging from 2.63–2.89 Å. In the eighth Pd site, Pd is bonded in a 4-coordinate geometry to nine Pd and four Sb atoms. There are a spread of Pd–Sb bond distances ranging from 2.63–2.90 Å. There are four inequivalent Sb sites. In the first Sb site, Sb is bonded in a 10-coordinate geometry to ten Pd atoms. In the second Sb site, Sb is bonded in a distorted q6 geometry to ten Pd atoms. In the third Sb site, Sb is bonded in a body-centered cubic geometry to eight Pd atoms. In the fourth Sb site, Sb is bonded in a distorted q6 geometry to ten Pd atoms.
