Materials Data on LaSi2Ru by Materials Project

Abstract

LaRuSi2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine Si4- atoms. There are a spread of La–Si bond distances ranging from 3.06–3.34 Å. Ru5+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are a spread of Ru–Si bond distances ranging from 2.40–2.46 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 4-coordinate geometry to three equivalent La3+, four equivalent Ru5+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.60 Å. In the second Si4- site, Si4- is bonded in a 1-coordinate geometry to six equivalent La3+, one Ru5+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.54 Å.
