Materials Data on BAsO4 by Materials Project

BAsO4 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. B3+ is bonded to four equivalent O2- atoms to form BO4 tetrahedra that share corners with four equivalent AsO4 tetrahedra. All B–O bond lengths are 1.48 Å. As5+ is bonded to four equivalent O2- atoms to form AsO4 tetrahedra that share corners with four equivalent BO4 tetrahedra. All As–O bond lengths are 1.72 Å. O2- is bonded in a bent 120 degrees geometry to one B3+ and one As5+ atom.
