Materials Data on YTm3(SnPd2)4 by Materials Project

Abstract

Tm3Y(Pd2Sn)4 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a body-centered cubic geometry to eight Pd and six Sn atoms. There are a spread of Tm–Pd bond distances ranging from 2.89–2.94 Å. All Tm–Sn bond lengths are 3.38 Å. In the second Tm site, Tm is bonded in a body-centered cubic geometry to eight Pd and six equivalent Sn atoms. There are two shorter (2.91 Å) and six longer (2.94 Å) Tm–Pd bond lengths. All Tm–Sn bond lengths are 3.38 Å. Y is bonded in a body-centered cubic geometry to eight Pd and six equivalent Sn atoms. All Y–Pd bond lengths are 2.94 Å. All Y–Sn bond lengths are 3.39 Å. There are eight inequivalent Pd sites. In the first Pd site, Pd is bonded in a body-centered cubic geometry to four Tm and four equivalent Sn atoms. There are one shorter (2.92 Å) and three longer (2.94 Å) Pd–Tm bond lengths. There are one shorter (2.91 Å) and three longer (2.94 Å) Pd–Sn bond lengths. In the second Pd site, Pd is bonded in a body-centered cubic geometry to one Tm, three equivalent Y, and four equivalent Sn atoms. The Pd–Tm bond length is 2.89 Å. All Pd–Y bond lengths are 2.94 Å. There are three shorter (2.93 Å) and one longer (2.94 Å) Pd–Sn bond lengths. In the third Pd site, Pd is bonded in a body-centered cubic geometry to four Tm and four equivalent Sn atoms. There are one shorter (2.92 Å) and three longer (2.94 Å) Pd–Tm bond lengths. There are one shorter (2.91 Å) and three longer (2.94 Å) Pd–Sn bond lengths. In the fourth Pd site, Pd is bonded in a body-centered cubic geometry to four Tm and four Sn atoms. All Pd–Tm bond lengths are 2.94 Å. There are one shorter (2.91 Å) and three longer (2.94 Å) Pd–Sn bond lengths. In the fifth Pd site, Pd is bonded in a body-centered cubic geometry to four Tm and four equivalent Sn atoms. There are one shorter (2.91 Å) and three longer (2.94 Å) Pd–Sn bond lengths. In the sixth Pd site, Pd is bonded in a body-centered cubic geometry to one Tm, three equivalent Y, and four equivalent Sn atoms. There are three shorter (2.93 Å) and one longer (2.94 Å) Pd–Sn bond lengths. In the seventh Pd site, Pd is bonded in a body-centered cubic geometry to three equivalent Tm, one Y, and four Sn atoms. There are one shorter (2.89 Å) and three longer (2.94 Å) Pd–Sn bond lengths. In the eighth Pd site, Pd is bonded in a body-centered cubic geometry to four Tm and four Sn atoms. There are one shorter (2.91 Å) and three longer (2.94 Å) Pd–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a distorted body-centered cubic geometry to six Tm and eight Pd atoms. In the second Sn site, Sn is bonded in a distorted body-centered cubic geometry to three equivalent Tm, three equivalent Y, and eight Pd atoms.
