Materials Data on HoAu3 by Materials Project
HoAu3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Ho3+ is bonded to twelve Au1- atoms to form a mixture of corner, edge, and face-sharing HoAu12 cuboctahedra. There are a spread of Ho–Au bond distances ranging from 3.00–3.09 Å. There are two inequivalent Au1- sites. In the first Au1- site, Au1- is bonded in a 12-coordinate geometry to four equivalent Ho3+ atoms. In the second Au1- site, Au1- is bonded in a distorted see-saw-like geometry to four equivalent Ho3+ atoms.
