The material described by AgHgAsO4 crystallizes in the orthorhombic Fdd2 space group. Ag(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Hg(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. As(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ag(1), one Hg(1), and one As(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ag(1), one Hg(1), and one As(1) atom. is represented by the CIF card [CIF]
