Materials Data on Si3P by Materials Project
Si3P is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a distorted body-centered cubic geometry to four equivalent Si+1.33- and four equivalent P4+ atoms. All Si–Si bond lengths are 2.66 Å. All Si–P bond lengths are 2.66 Å. In the second Si+1.33- site, Si+1.33- is bonded in a body-centered cubic geometry to eight equivalent Si+1.33- atoms. P4+ is bonded in a body-centered cubic geometry to eight equivalent Si+1.33- atoms.
