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, Re(1) is bonded in a 8-coordinate geometry to one F(3), one F(5), two equivalent F(1), two equivalent F(2), and two equivalent F(4) atoms. There are five inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Re(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Re(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to one Re(1) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one Re(1) atom. In the fifth F site, F(5) is bonded in a single-bond geometry to one Re(1) atom.
