The structure described by AgHg2AsO4 crystallizes in the orthorhombic Pbam space group. Ag(1) is bonded in an L-shaped geometry to two equivalent O(2) atoms. Hg(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. As(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Hg(1) and one As(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ag(1), one Hg(1), and one As(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Hg(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
