Materials Data on Yb3Si5 by Materials Project
Yb3Si5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Yb is bonded in a 10-coordinate geometry to ten Si atoms. There are a spread of Yb–Si bond distances ranging from 3.10–3.20 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Si atoms. All Si–Si bond lengths are 2.36 Å. In the second Si site, Si is bonded in a 8-coordinate geometry to six equivalent Yb and two equivalent Si atoms.
