Materials Data on K8AsO3 by Materials Project
K8AsO3 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K1+ is bonded to one As2- and three equivalent O2- atoms to form a mixture of distorted edge and corner-sharing KAsO3 tetrahedra. The K–As bond length is 3.17 Å. All K–O bond lengths are 2.93 Å. As2- is bonded in a body-centered cubic geometry to eight equivalent K1+ atoms. O2- is bonded in a body-centered cubic geometry to eight equivalent K1+ atoms.
