Materials Data on ErCoSn by Materials Project
ErCoSn crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er is bonded in a 9-coordinate geometry to four equivalent Co and six equivalent Sn atoms. There are a spread of Er–Co bond distances ranging from 2.92–3.04 Å. There are a spread of Er–Sn bond distances ranging from 3.10–3.24 Å. Co is bonded in a 8-coordinate geometry to four equivalent Er and four equivalent Sn atoms. There are two shorter (2.61 Å) and two longer (2.63 Å) Co–Sn bond lengths. Sn is bonded in a 10-coordinate geometry to six equivalent Er and four equivalent Co atoms.
