Materials Data on HoCu4Au by Materials Project

Abstract

HoAuCu4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ho is bonded in a 4-coordinate geometry to four equivalent Au and twelve equivalent Cu atoms. All Ho–Au bond lengths are 3.09 Å. All Ho–Cu bond lengths are 2.96 Å. Au is bonded in a 4-coordinate geometry to four equivalent Ho and twelve equivalent Cu atoms. All Au–Cu bond lengths are 2.96 Å. Cu is bonded to three equivalent Ho, three equivalent Au, and six equivalent Cu atoms to form a mixture of corner, edge, and face-sharing CuHo3Cu6Au3 cuboctahedra. There are three shorter (2.51 Å) and three longer (2.54 Å) Cu–Cu bond lengths.
