Materials Data on Ho5Si3 by Materials Project

Ho5Si3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 3-coordinate geometry to five equivalent Si atoms. There are a spread of Ho–Si bond distances ranging from 2.90–3.41 Å. In the second Ho site, Ho is bonded in a 6-coordinate geometry to six equivalent Si atoms. All Ho–Si bond lengths are 3.03 Å. Si is bonded in a 9-coordinate geometry to nine Ho atoms.
