Materials Data on Na2SO2 by Materials Project
Na2SO2 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Na1+ is bonded in a 2-coordinate geometry to three equivalent O2- atoms. There are a spread of Na–O bond distances ranging from 2.28–2.79 Å. S2+ is bonded in a linear geometry to two equivalent O2- atoms. Both S–O bond lengths are 1.71 Å. O2- is bonded in a 3-coordinate geometry to three equivalent Na1+ and one S2+ atom.
