The crystal structure described by LiAs(HO2)2 crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra and corners with four equivalent As(1)O4 tetrahedra. 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 four equivalent Li(1)O4 tetrahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(2) and one O(4) atom. In the second H site, H(2) is bonded in a linear geometry to one O(2) and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Li(1) and one As(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one As(1), one H(1), and one H(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one As(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Li(1), one As(1), and one H(1) atom. is represented by the CIF file [CIF]
