Materials Data on K(AsRu)2 by Materials Project
K(RuAs)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight equivalent As3- atoms. All K–As bond lengths are 3.50 Å. Ru+2.50+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing RuAs4 tetrahedra. All Ru–As bond lengths are 2.43 Å. As3- is bonded in a 8-coordinate geometry to four equivalent K1+ and four equivalent Ru+2.50+ atoms.
