Materials Data on CeSi3Ru by Materials Project
CeRuSi3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Ce is bonded in a 4-coordinate geometry to five equivalent Ru and twelve Si atoms. There are four shorter (3.37 Å) and one longer (3.40 Å) Ce–Ru bond lengths. There are a spread of Ce–Si bond distances ranging from 3.05–3.41 Å. Ru is bonded in a 5-coordinate geometry to five equivalent Ce and five Si atoms. There are one shorter (2.34 Å) and four longer (2.36 Å) Ru–Si bond lengths. There are two inequivalent Si sites. In the first Si site, Si is bonded in a distorted bent 120 degrees geometry to four equivalent Ce, two equivalent Ru, and two equivalent Si atoms. Both Si–Si bond lengths are 2.61 Å. In the second Si site, Si is bonded in a 1-coordinate geometry to four equivalent Ce, one Ru, and four equivalent Si atoms.
