The structure described by (NO)2Se2O3 is Indium-derived structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of eight nitroxyl molecules and four Se2O3 clusters. In each Se2O3 cluster, there are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a water-like geometry to one O(1) and one O(3) atom. In the second Se site, Se(2) is bonded in a water-like geometry to one O(3) and one O(5) atom. There are three inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to one Se(2) atom. In the second O site, O(1) is bonded in a single-bond geometry to one Se(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Se(1) and one Se(2) atom. is represented by the CIF file [CIF]
