The structure described by (U(NO3)2)2O2 is Indium-derived structured and crystallizes in the orthorhombic Pbcn space group. The structure is zero-dimensional and consists of four water atoms and four U(NO3)2 clusters. In each U(NO3)2 cluster, U(1) is bonded in a distorted linear geometry to two equivalent O(1) and two equivalent O(2) atoms. N(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one U(1) and one N(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one U(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one N(1) atom. is represented by the CIF file [CIF]
