Materials Data on ZnAs3 by Materials Project
ZnAs3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Zn2+ is bonded in a body-centered cubic geometry to eight equivalent As+0.67- atoms. All Zn–As bond lengths are 2.90 Å. There are two inequivalent As+0.67- sites. In the first As+0.67- site, As+0.67- is bonded in a distorted body-centered cubic geometry to four equivalent Zn2+ and four equivalent As+0.67- atoms. All As–As bond lengths are 2.90 Å. In the second As+0.67- site, As+0.67- is bonded in a body-centered cubic geometry to eight equivalent As+0.67- atoms.
