Materials Data on Si3Ru2 by Materials Project
Ru2Si3 is Magnesium tetraboride-like structured and crystallizes in the tetragonal P-4c2 space group. The structure is three-dimensional. there are three inequivalent Ru2+ sites. In the first Ru2+ site, Ru2+ is bonded in a 8-coordinate geometry to eight Si+1.33- atoms. There are four shorter (2.44 Å) and four longer (2.61 Å) Ru–Si bond lengths. In the second Ru2+ site, Ru2+ is bonded in a 6-coordinate geometry to six Si+1.33- atoms. There are four shorter (2.32 Å) and two longer (2.61 Å) Ru–Si bond lengths. In the third Ru2+ site, Ru2+ is bonded in a 6-coordinate geometry to eight Si+1.33- atoms. There are a spread of Ru–Si bond distances ranging from 2.35–2.89 Å. There are two inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a 2-coordinate geometry to five Ru2+ atoms. In the second Si+1.33- site, Si+1.33- is bonded in a 4-coordinate geometry to five Ru2+ atoms.
