Materials Data on TcAs3 by Materials Project
TcAs3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tc1+ is bonded in a distorted body-centered cubic geometry to fourteen As+0.33- atoms. There are eight shorter (2.79 Å) and six longer (3.22 Å) Tc–As bond lengths. There are two inequivalent As+0.33- sites. In the first As+0.33- site, As+0.33- is bonded in a distorted body-centered cubic geometry to four equivalent Tc1+ and four equivalent As+0.33- atoms. All As–As bond lengths are 2.79 Å. In the second As+0.33- site, As+0.33- is bonded in a 8-coordinate geometry to six equivalent Tc1+ and eight equivalent As+0.33- atoms.
