Materials Data on Tc3H by Materials Project
Tc3H is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Tc+0.33- sites. In the first Tc+0.33- site, Tc+0.33- is bonded in a 8-coordinate geometry to four equivalent Tc+0.33- and four equivalent H1+ atoms. All Tc–Tc bond lengths are 2.56 Å. All Tc–H bond lengths are 2.56 Å. In the second Tc+0.33- site, Tc+0.33- is bonded in a body-centered cubic geometry to eight equivalent Tc+0.33- atoms. H1+ is bonded in a distorted body-centered cubic geometry to eight equivalent Tc+0.33- atoms.
