Materials Data on ErCuSn by Materials Project
ErCuSn is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Er is bonded to six equivalent Cu and six equivalent Sn atoms to form a mixture of face and edge-sharing ErCu6Sn6 cuboctahedra. All Er–Cu bond lengths are 3.18 Å. All Er–Sn bond lengths are 3.18 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent Sn atoms. All Cu–Sn bond lengths are 2.61 Å. Sn is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent Cu atoms.
