The structure described by WAsO5 crystallizes in the monoclinic P2_1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(10), one O(2), one O(3), one O(4), and one O(7) atom to form distorted WO6 octahedra that share corners with two equivalent As(1)O4 tetrahedra and edges with two equivalent W(2)O6 octahedra. In the second W site, W(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(8), and one O(9) atom to form distorted WO6 octahedra that share corners with two equivalent As(1)O4 tetrahedra and edges with two equivalent W(1)O6 octahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded to one O(3), one O(5), one O(7), and one O(9) atom to form AsO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra and corners with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-55°. In the second As site, As(2) is bonded in a distorted trigonal non-coplanar geometry to one O(5), one O(6), and one O(8) atom. There are ten inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one As(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one As(1) and one As(2) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one As(2) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one W(1) and one As(1) atom. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one W(2) and one As(2) atom. In the ninth O site, O(9) is bonded in a distorted bent 120 degrees geometry to one W(2) and one As(1) atom. In the tenth O site, O(10) is bonded in a single-bond geometry to one W(1) atom. is represented by the CIF file [CIF]
