Materials Data on Na3AgS2 by Materials Project
Na3AgS2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four equivalent S2- atoms to form a mixture of corner and edge-sharing NaS4 tetrahedra. All Na–S bond lengths are 2.83 Å. In the second Na1+ site, Na1+ is bonded to four equivalent S2- atoms to form a mixture of corner and edge-sharing NaS4 tetrahedra. There are two shorter (2.78 Å) and two longer (2.87 Å) Na–S bond lengths. Ag1+ is bonded in a linear geometry to two equivalent S2- atoms. Both Ag–S bond lengths are 2.41 Å. S2- is bonded to six Na1+ and one Ag1+ atom to form a mixture of distorted corner and edge-sharing SNa6Ag pentagonal bipyramids.
