The structure described by UO3(CO2)2 is Cyanogen Chloride-like structured and crystallizes in the orthorhombic Fdd2 space group. The structure is zero-dimensional and consists of sixteen carbon dioxide molecules and eight UO3 clusters. In each UO3 cluster, U(1) is bonded in a distorted T-shaped geometry to one O(4) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) atom. In the second O site, O(4) is bonded in a single-bond geometry to one U(1) atom. is represented by the CIF card [CIF]
