The material structure described by InAsH2O5 crystallizes in the triclinic P-1 space group. In(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form InO6 octahedra that share corners with five equivalent As(1)O4 tetrahedra and  an edgeedge with one In(1)O6 octahedra. As(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AsO4 tetrahedra that share corners with five equivalent In(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(5) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent In(1) and one As(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one In(1), one As(1), and one H(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one In(1) and one As(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one In(1) and one As(1) atom. In the fifth O site, O(5) is bonded in a distorted water-like geometry to one In(1), one H(1), and one H(2) atom. is represented by the CIF file [CIF]
