Materials Data on Sn(SO2)2 by Materials Project

Abstract

Sn(SO2)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Sn(SO2)2 clusters. Sn4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.28–2.33 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a water-like geometry to two O2- atoms. Both S–O bond lengths are 1.53 Å. In the second S2+ site, S2+ is bonded in a water-like geometry to two O2- atoms. Both S–O bond lengths are 1.53 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Sn4+ and one S2+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Sn4+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn4+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Sn4+ and one S2+ atom.
