Materials Data on ReN2(OF4)2 by Materials Project

ReF8(NO)2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of eight nitroxyl molecules and four ReF8 clusters. In each ReF8 cluster, Re4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Re–F bond distances ranging from 1.93–1.99 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one Re4+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to one Re4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Re4+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Re4+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Re4+ atom.

Materials Data on ReN(OF2)3 by Materials Project

ReOF6NO2 is alpha Pu-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight hydroxylamine, n-hydroxy- molecules and eight ReOF6 clusters. In each ReOF6 cluster, Re7+ is bonded in a pentagonal bipyramidal geometry to one O2- and six F1- atoms. The Re–O bond length is 1.71 Å. There are a spread of Re–F bond distances ranging from 1.92–1.97 Å. O2- is bonded in a single-bond geometry to one Re7+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to one Re7+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom.
