Materials Data on HoCu4Ag by Materials Project

Abstract

HoCu4Ag crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to four equivalent Ag and twelve equivalent Cu atoms. All Ho–Ag bond lengths are 3.09 Å. All Ho–Cu bond lengths are 2.96 Å. Ag is bonded in a 4-coordinate geometry to four equivalent Ho and twelve equivalent Cu atoms. All Ag–Cu bond lengths are 2.96 Å. Cu is bonded to three equivalent Ho, three equivalent Ag, and six equivalent Cu atoms to form a mixture of edge, face, and corner-sharing CuHo3Cu6Ag3 cuboctahedra. There are three shorter (2.51 Å) and three longer (2.54 Å) Cu–Cu bond lengths.
