The material structure described by CAs2H6O6 crystallizes in the orthorhombic Aea2 space group. C(1) is bonded in a distorted tetrahedral geometry to two equivalent As(1) and two equivalent H(3) atoms. As(1) is bonded to one C(1), one O(1), one O(2), and one O(3) atom to form corner-sharing AsCO3 tetrahedra. There are three 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 linear geometry to one O(2) and one O(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one As(1) and one H(1) atom. In the second O site, O(2) is bonded in a water-like geometry to one As(1) and one H(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one As(1), one H(1), and one H(2) atom. is represented by the CIF file [CIF]
