Materials Data on U(N3O7)2 by Materials Project
UO2(NO3)2N2(NO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules, four nitric acid molecules, and two UO2(NO3)2 clusters. In each UO2(NO3)2 cluster, U6+ is bonded in a distorted linear geometry to four O2- atoms. There are two shorter (1.79 Å) and two longer (2.48 Å) U–O bond lengths. N+3.67+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.24 Å) and one longer (1.28 Å) N–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+3.67+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+3.67+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one U6+ and one N+3.67+ atom.
