Materials Data on CeSi5 by Materials Project
CeSi5 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Ce4+ is bonded in a 10-coordinate geometry to fourteen Si+0.80- atoms. There are a spread of Ce–Si bond distances ranging from 3.02–3.28 Å. There are two inequivalent Si+0.80- sites. In the first Si+0.80- site, Si+0.80- is bonded in a 8-coordinate geometry to three equivalent Ce4+ and five Si+0.80- atoms. There are a spread of Si–Si bond distances ranging from 2.39–2.74 Å. In the second Si+0.80- site, Si+0.80- is bonded in a distorted q6 geometry to two equivalent Ce4+ and eight equivalent Si+0.80- atoms.
