H6Se3(NO5)2NO2 is Indium-derived structured and crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of two nitrous acid molecules and two H6Se3(NO5)2 clusters. In each H6Se3(NO5)2 cluster, N(1) is bonded in a distorted trigonal planar geometry to one H(1), one H(3), and one O(4) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one N(1) and one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Se site, Se(2) is bonded in a distorted trigonal non-coplanar geometry to one O(3), one O(4), and one O(6) atom. There are five inequivalent O sites. In the first O site, O(6) is bonded in a single-bond geometry to one Se(2) atom. In the second O site, O(1) is bonded in a water-like geometry to one H(1) and one Se(1) atom. In the third O site, O(2) is bonded in a single-bond geometry to one Se(1) atom. In the fourth O site, O(3) is bonded in a water-like geometry to one H(2) and one Se(2) atom. In the fifth O site, O(4) is bonded in a bent 120 degrees geometry to one N(1) and one Se(2) atom.
