The crystal structure described by CAs2H5O6 crystallizes in the monoclinic Cc space group. C(1) is bonded in a trigonal planar geometry to one As(1), one As(2), and one H(5) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded to one C(1), one O(1), one O(3), and one O(5) atom to form corner-sharing AsCO3 tetrahedra. In the second As site, As(2) is bonded to one C(1), one O(2), one O(4), and one O(6) atom to form corner-sharing AsCO3 tetrahedra. There are five inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(2) and one O(5) atom. In the second H site, H(2) is bonded in a linear geometry to one O(1) and one O(6) atom. In the third H site, H(3) is bonded in a linear geometry to one O(1) and one O(3) atom. In the fourth H site, H(4) is bonded in a linear geometry to one O(2) and one O(4) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(1) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one As(1), one H(2), and one H(3) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one As(2), one H(1), and one H(4) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one As(1) and one H(3) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one As(2) and one H(4) atom. In the fifth O site, O(5) is bonded in a water-like geometry to one As(1) and one H(1) atom. In the sixth O site, O(6) is bonded in a water-like geometry to one As(2) and one H(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
