Os3C8H2(SO4)2 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Os3C8H2(SO4)2 clusters. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to two equivalent C(1), two equivalent H(1), and two equivalent S(1) atoms to form distorted face-sharing OsH2C2S2 octahedra. In the second Os site, Os(2) is bonded to one C(2), one C(3), one C(4), one H(1), and two equivalent S(1) atoms to form distorted OsHC3S2 octahedra that share  an edgeedge with one Os(2)HC3S2 octahedra and  a faceface with one Os(1)H2C2S2 octahedra. There are four inequivalent C sites. In the first C site, C(4) is bonded in a linear geometry to one Os(2) and one O(3,4) atom. In the second C site, C(1) is bonded in a linear geometry to one Os(1) and one O(1) atom. In the third C site, C(2) is bonded in a linear geometry to one Os(2) and one O(2) atom. In the fourth C site, C(3) is bonded in a linear geometry to one Os(2) and one O(3,4) atom. H(1) is bonded in an L-shaped geometry to one Os(1) and one Os(2) atom. S(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Os(2) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one C(2) atom. In the second O site, O(3,4) is bonded in a single-bond geometry to one C(3) atom. In the third O site, O(1) is bonded in a single-bond geometry to one C(1) atom.
