Materials Data on Ho3Fe2Si3 by Materials Project
Ho3Fe2Si3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 4-coordinate geometry to four equivalent Fe and five Si atoms. All Ho–Fe bond lengths are 3.18 Å. There are a spread of Ho–Si bond distances ranging from 2.84–3.27 Å. In the second Ho site, Ho is bonded in a 10-coordinate geometry to four equivalent Fe and seven Si atoms. There are a spread of Ho–Fe bond distances ranging from 2.99–3.11 Å. There are a spread of Ho–Si bond distances ranging from 2.93–3.28 Å. Fe is bonded in a 10-coordinate geometry to six Ho and four Si atoms. There are a spread of Fe–Si bond distances ranging from 2.32–2.59 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to seven Ho and two equivalent Fe atoms. In the second Si site, Si is bonded in a 10-coordinate geometry to six Ho, three equivalent Fe, and one Si atom. The Si–Si bond length is 2.81 Å.
