The compound described by UO2CO3(N2)2(CO3)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight 463-79-6 molecules, sixteen ammonia atoms, and four UO2CO3 clusters. In each UO2CO3 cluster, U(1) is bonded in a distorted linear geometry to two equivalent O(1) and two equivalent O(6) atoms. C(1) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one U(1) and one C(1) atom. In the second O site, O(4) is bonded in a single-bond geometry to one C(1) atom. In the third O site, O(6) is bonded in a single-bond geometry to one U(1) atom. is represented by the CIF file [CIF]
