Materials Data on BaAgAs by Materials Project
BaAgAs crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ba2+ is bonded to six equivalent Ag1+ and six equivalent As3- atoms to form a mixture of distorted edge and face-sharing BaAg6As6 cuboctahedra. All Ba–Ag bond lengths are 3.53 Å. All Ba–As bond lengths are 3.53 Å. Ag1+ is bonded in a trigonal planar geometry to six equivalent Ba2+ and three equivalent As3- atoms. All Ag–As bond lengths are 2.70 Å. As3- is bonded in a 3-coordinate geometry to six equivalent Ba2+ and three equivalent Ag1+ atoms.
