Materials Data on Lu5Si3 by Materials Project
Lu5Si3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 6-coordinate geometry to six equivalent Si atoms. All Lu–Si bond lengths are 2.96 Å. In the second Lu site, Lu is bonded in a 5-coordinate geometry to five equivalent Si atoms. There are a spread of Lu–Si bond distances ranging from 2.84–3.33 Å. Si is bonded in a 9-coordinate geometry to nine Lu atoms.
