C2N4H8S2II is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four hydriodic acid atoms and four C2N4H8S2I clusters. In each C2N4H8S2I cluster, C(1) is bonded in a distorted trigonal planar geometry to one N(1), one N(2), and one S(1) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one C(1), one H(1), and one H(2) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(1), one H(3), and one H(4) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(2) atom. S(1) is bonded in a water-like geometry to one C(1) and one I(1) atom. I(1) is bonded in a linear geometry to two equivalent S(1) atoms.
