Materials Data on Na3AuS2 by Materials Project
Na3AuS2 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to two equivalent Au1+ and four equivalent S2- atoms. Both Na–Au bond lengths are 3.11 Å. There are two shorter (2.88 Å) and two longer (2.93 Å) Na–S bond lengths. Au1+ is bonded in a body-centered cubic geometry to six equivalent Na1+ and two equivalent S2- atoms. Both Au–S bond lengths are 2.33 Å. S2- is bonded in a 7-coordinate geometry to six equivalent Na1+ and one Au1+ atom.
