Materials Data on Na2S2O3 by Materials Project
Na2S2O3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four hydrogen sulfide molecules and one Na2SO3 framework. In the Na2SO3 framework, there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.39–2.60 Å. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.39–2.62 Å. S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.49 Å) and one longer (1.50 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Na1+ and one S2+ atom to form a mixture of distorted edge and corner-sharing ONa3S tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Na1+ and one S2+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one S2+ atom.
