Materials Data on Ba3As2 by Materials Project
Ba3AsAs is alpha Rhenium trioxide-like structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one arsenic molecule and one Ba3As framework. In the Ba3As framework, Ba2+ is bonded in a linear geometry to two equivalent As3- atoms. Both Ba–As bond lengths are 3.09 Å. As3- is bonded to six equivalent Ba2+ atoms to form corner-sharing AsBa6 octahedra. The corner-sharing octahedral tilt angles are 0°.
