Ag(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(7), and one O(8) atom. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(6), one O(7), and one O(8) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second As site, As(2) is bonded in a tetrahedral geometry to one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites.

In the fifth O site, O(1) is bonded in a single-bond geometry to one Ag(1) and one As(1) atom. In the sixth O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Ag(1), one Cu(1), and one As(1) atom. In the seventh O site, O(3) is bonded in a bent 120 degrees geometry to one Ag(1) and one As(1) atom.
