Materials Data on Na3SbSe4 by Materials Project
Na3SbSe4 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are four shorter (3.11 Å) and four longer (3.60 Å) Na–Se bond lengths. Sb5+ is bonded in a tetrahedral geometry to four equivalent Se2- atoms. All Sb–Se bond lengths are 2.52 Å. Se2- is bonded in a 4-coordinate geometry to six equivalent Na1+ and one Sb5+ atom.
