Materials Data on Ba4As3 by Materials Project
Ba4As3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Ba2+ is bonded to six equivalent As+2.67- atoms to form a mixture of distorted corner, edge, and face-sharing BaAs6 octahedra. The corner-sharing octahedra tilt angles range from 20–48°. There are three shorter (3.32 Å) and three longer (3.66 Å) Ba–As bond lengths. As+2.67- is bonded in a 8-coordinate geometry to eight equivalent Ba2+ atoms.
