The material structure described by H9O4H7O3(H7SO7)2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two hydrogen tetrahydrate molecules, two molecular hydrogen;trihydrate molecules, and four H7SO7 clusters. In each H7SO7 cluster, there are seven inequivalent H sites. In the first H site, H(10) is bonded in a single-bond geometry to one O(6) atom. In the second H site, H(11) is bonded in a single-bond geometry to one O(6) atom. In the third H site, H(12) is bonded in a single-bond geometry to one O(7) atom. In the fourth H site, H(13) is bonded in a single-bond geometry to one O(7) atom. In the fifth H site, H(14) is bonded in a distorted linear geometry to one O(11) and one O(8) atom. In the sixth H site, H(15) is bonded in a distorted linear geometry to one O(6) and one O(8) atom. In the seventh H site, H(16) is bonded in a linear geometry to one O(7) and one O(8) atom. S(1) is bonded in a tetrahedral geometry to one O(10), one O(11), one O(12), and one O(9) atom. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a distorted water-like geometry to one H(10), one H(11), and one H(15) atom. In the second O site, O(7) is bonded in a trigonal non-coplanar geometry to one H(12), one H(13), and one H(16) atom. In the third O site, O(8) is bonded in a trigonal non-coplanar geometry to one H(14), one H(15), and one H(16) atom. In the fourth O site, O(9) is bonded in a single-bond geometry to one S(1) atom. In the fifth O site, O(10) is bonded in a distorted single-bond geometry to one S(1) atom. In the sixth O site, O(11) is bonded in a distorted bent 120 degrees geometry to one H(14) and one S(1) atom. In the seventh O site, O(12) is bonded in a distorted single-bond geometry to one S(1) atom. is represented by the CIF card [CIF]
