Materials Data on Cs(CoAs)2 by Materials Project
Cs(CoAs)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cs1+ is bonded in a distorted body-centered cubic geometry to eight equivalent As3- atoms. All Cs–As bond lengths are 3.66 Å. Co+2.50+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing CoAs4 tetrahedra. All Co–As bond lengths are 2.31 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Cs1+ and four equivalent Co+2.50+ atoms.
