Materials Data on Be2CoSi by Materials Project
Be2CoSi is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Be sites. In the first Be site, Be is bonded in a 4-coordinate geometry to four equivalent Be, six equivalent Co, and four equivalent Si atoms. All Be–Be bond lengths are 2.31 Å. All Be–Co bond lengths are 2.66 Å. All Be–Si bond lengths are 2.31 Å. In the second Be site, Be is bonded in a 4-coordinate geometry to four equivalent Be, four equivalent Co, and six equivalent Si atoms. All Be–Co bond lengths are 2.31 Å. All Be–Si bond lengths are 2.66 Å. Co is bonded in a 8-coordinate geometry to ten Be and four equivalent Si atoms. All Co–Si bond lengths are 2.31 Å. Si is bonded in a 8-coordinate geometry to ten Be and four equivalent Co atoms.
