Materials Data on YbSnAu by Materials Project

Abstract

YbAuSn crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are four inequivalent Yb sites. In the first Yb site, Yb is bonded in a 12-coordinate geometry to six Au and six Sn atoms. There are a spread of Yb–Au bond distances ranging from 3.16–3.42 Å. There are a spread of Yb–Sn bond distances ranging from 3.26–3.41 Å. In the second Yb site, Yb is bonded in a 12-coordinate geometry to six Au and six Sn atoms. There are four shorter (3.42 Å) and two longer (3.46 Å) Yb–Au bond lengths. There are two shorter (3.23 Å) and four longer (3.25 Å) Yb–Sn bond lengths. In the third Yb site, Yb is bonded in a 12-coordinate geometry to six Au and six Sn atoms. There are a spread of Yb–Au bond distances ranging from 3.24–3.37 Å. There are a spread of Yb–Sn bond distances ranging from 3.31–3.38 Å. In the fourth Yb site, Yb is bonded in a 12-coordinate geometry to six Au and six Sn atoms. There are two shorter (3.32 Å) and four longer (3.35 Å) Yb–Au bond lengths. There are four shorter (3.34 Å) and two longer (3.39 Å) Yb–Sn bond lengths. There are three inequivalent Au sites. In the first Au site, Au is bonded in a 9-coordinate geometry to six Yb and three Sn atoms. There are one shorter (2.75 Å) and two longer (2.77 Å) Au–Sn bond lengths. In the second Au site, Au is bonded in a 10-coordinate geometry to six Yb and four Sn atoms. There are three shorter (2.77 Å) and one longer (3.16 Å) Au–Sn bond lengths. In the third Au site, Au is bonded in a 10-coordinate geometry to six Yb and four Sn atoms. There are a spread of Au–Sn bond distances ranging from 2.77–2.96 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 3-coordinate geometry to six Yb, three Au, and one Sn atom. The Sn–Sn bond length is 2.99 Å. In the second Sn site, Sn is bonded in a 10-coordinate geometry to six Yb and four Au atoms. In the third Sn site, Sn is bonded in a 3-coordinate geometry to six Yb and four Au atoms.
