Materials Data on Rb2S2NO6 by Materials Project
Rb2NS2O6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.49 Å. N2- is bonded in a bent 120 degrees geometry to two equivalent S6+ atoms. Both N–S bond lengths are 1.69 Å. S6+ is bonded to one N2- and three O2- atoms to form corner-sharing SNO3 tetrahedra. There is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to three equivalent Rb1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S6+ atom.
