Materials Data on IN2O4F5 by Materials Project
NONO3IF5 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two nitric acid molecules, two nitroxyl molecules, and two IF5 clusters. In each IF5 cluster, I5+ is bonded in a square pyramidal geometry to five F1- atoms. There are a spread of I–F bond distances ranging from 1.86–1.95 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one I5+ atom.
