Materials Data on Ba(AsRu)2 by Materials Project
BaRu2As2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight equivalent As3- atoms. All Ba–As bond lengths are 3.51 Å. Ru2+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing RuAs4 tetrahedra. All Ru–As bond lengths are 2.44 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Ba2+ and four equivalent Ru2+ atoms.
