IrSO4Cl3SO3 is Indium-derived structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two sulfur trioxide molecules and two IrSO4Cl3 clusters. In each IrSO4Cl3 cluster, Ir(1) is bonded to one O(1), one O(2), one Cl(1), and two equivalent Cl(2) atoms to form distorted IrCl3O2 trigonal bipyramids that share  an edgeedge with one S(2)O4 tetrahedra. S(2) is bonded to one O(1), one O(2), and two equivalent O(5) atoms to form SO4 tetrahedra that share  an edgeedge with one Ir(1)Cl3O2 trigonal bipyramid. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Ir(1) and one S(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one Ir(1) and one S(2) atom. In the third O site, O(5) is bonded in a single-bond geometry to one S(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Ir(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Ir(1) atom.
