The structure described by BaBAsO5 crystallizes in the trigonal P3_121 space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. B(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form BO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra and corners with two equivalent As(1)O4 tetrahedra. As(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form AsO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(1) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one As(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(1), one B(1), and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
