Materials Data on Co2Si by Materials Project

Co2Si is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded in a 5-coordinate geometry to five equivalent Si4- atoms. There are a spread of Co–Si bond distances ranging from 2.29–2.60 Å. In the second Co2+ site, Co2+ is bonded in a 5-coordinate geometry to five equivalent Si4- atoms. There are a spread of Co–Si bond distances ranging from 2.33–2.57 Å. Si4- is bonded in a 10-coordinate geometry to ten Co2+ atoms.
