Title: Materials Data on HoCu5Sn by Materials Project

Abstract

HoCu5Sn crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ho is bonded in a 6-coordinate geometry to fifteen Cu and four equivalent Sn atoms. There are a spread of Ho–Cu bond distances ranging from 2.88–3.41 Å. There are two shorter (3.29 Å) and two longer (3.41 Å) Ho–Sn bond lengths. There are four inequivalent Cu sites. In the first Cu site, Cu is bonded to three equivalent Ho, seven Cu, and two equivalent Sn atoms to form a mixture of corner, edge, and face-sharing CuHo3Cu7Sn2 cuboctahedra. There are a spread of Cu–Cu bond distances ranging from 2.50–2.59 Å. Both Cu–Sn bond lengths are 2.81 Å. In the second Cu site, Cu is bonded to three equivalent Ho, seven Cu, and two equivalent Sn atoms to form a mixture of corner, edge, and face-sharing CuHo3Cu7Sn2 cuboctahedra. There are a spread of Cu–Cu bond distances ranging from 2.48–2.57 Å. There are one shorter (2.77 Å) and one longer (2.79 Å) Cu–Sn bond lengths. In the third Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Ho, six Cu, and one Sn atom. The Cu–Cu bond length is 3.05 Å. The Cu–Sn bond length is 2.79 Å.more » In the fourth Cu site, Cu is bonded in a 4-coordinate geometry to three equivalent Ho, five Cu, and three equivalent Sn atoms. There are one shorter (2.63 Å) and two longer (3.01 Å) Cu–Sn bond lengths. Sn is bonded in a 1-coordinate geometry to four equivalent Ho and ten Cu atoms.« less
