Materials Data on Na3Si by Materials Project

Na3Si is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Na sites. In the first Na site, Na is bonded to four equivalent Na and four equivalent Si atoms to form a mixture of distorted edge, corner, and face-sharing NaNa4Si4 tetrahedra. All Na–Na bond lengths are 3.17 Å. All Na–Si bond lengths are 3.17 Å. In the second Na site, Na is bonded in a body-centered cubic geometry to eight equivalent Na atoms. Si is bonded in a body-centered cubic geometry to eight equivalent Na atoms.
