Ag(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(5), one O(7), and two equivalent O(2) atoms. There are three inequivalent As sites. In the first As site, As(1) is bonded to one O(1), one O(2), one O(4), and one O(6) atom to form corner-sharing AsO4 tetrahedra. The corner-sharing octahedral tilt angles range from 48-51°.

There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(1) and one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(7) atom. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Ag(1), one As(1), and one H(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ag(1) and one As(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ag(1), one As(2), and one H(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one As(1) and one As(3) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Ag(1) and two equivalent As(3) atoms. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one As(1) and one As(3) atom. In the seventh O site, O(7) is bonded in a 2-coordinate geometry to one Ag(1), one As(2), and one H(2) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one As(2) and one As(3) atom.
