The crystal structure described by BAsO4 crystallizes in the tetragonal I-4 space group. B(1) is bonded to four equivalent O(1) atoms to form BO4 tetrahedra that share corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent B(1)O4 tetrahedra. O(1) is bonded in a bent 120 degrees geometry to one B(1) and one As(1) atom. is represented by the CIF card [CIF]
