Materials Data on Na8AsO3 by Materials Project

Na8AsO3 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na1+ is bonded to one As2- and three equivalent O2- atoms to form a mixture of distorted corner and edge-sharing NaAsO3 tetrahedra. The Na–As bond length is 2.76 Å. All Na–O bond lengths are 2.55 Å. As2- is bonded in a body-centered cubic geometry to eight equivalent Na1+ atoms. O2- is bonded in a body-centered cubic geometry to eight equivalent Na1+ atoms.
