The compound described by Cr(NH3)6(I)7 is Indium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two molecular iodine;dihydroiodide molecules, two Cr(NH3)6 clusters, and two I clusters. In each Cr(NH3)6 cluster, Cr(1) is bonded in an octahedral geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal non-coplanar geometry to one Cr(1), one H(1), one H(2), and one H(4) atom. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to one Cr(1), one H(5), and two equivalent H(3) atoms. There are five 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(1) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one N(2) atom. In each I cluster, there are two inequivalent I sites. In the first I site, I(3) is bonded in a linear geometry to two equivalent I(4) atoms. In the second I site, I(4) is bonded in a distorted single-bond geometry to one I(3) atom. is represented by the CIF card [CIF]
