Materials Data on LaCuSn by Materials Project
LaCuSn is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. La is bonded to six equivalent Cu and six equivalent Sn atoms to form a mixture of face and edge-sharing LaCu6Sn6 cuboctahedra. All La–Cu bond lengths are 3.36 Å. All La–Sn bond lengths are 3.36 Å. Cu is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Sn atoms. All Cu–Sn bond lengths are 2.66 Å. Sn is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Cu atoms.
