Materials Data on CrFeSi2 by Materials Project
FeSi(CrSi) is beta-prime palladium aluminum-derived structured and crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Cr5+ is bonded in a 7-coordinate geometry to seven Si4- atoms. There are a spread of Cr–Si bond distances ranging from 2.34–2.54 Å. Fe3+ is bonded in a 7-coordinate geometry to seven Si4- atoms. There are a spread of Fe–Si bond distances ranging from 2.25–2.53 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 7-coordinate geometry to three equivalent Cr5+ and four equivalent Fe3+ atoms. In the second Si4- site, Si4- is bonded in a 7-coordinate geometry to four equivalent Cr5+ and three equivalent Fe3+ atoms.
