Materials Data on K3Si by Materials Project
K3Si is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded to four equivalent K and four equivalent Si atoms to form a mixture of distorted face, edge, and corner-sharing KK4Si4 tetrahedra. All K–K bond lengths are 3.70 Å. All K–Si bond lengths are 3.70 Å. In the second K site, K is bonded in a body-centered cubic geometry to eight equivalent K atoms. Si is bonded in a body-centered cubic geometry to eight equivalent K atoms.
