Materials Data on BaAg2SnS4 by Materials Project

BaAg2SnS4 crystallizes in the orthorhombic I222 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (3.34 Å) and four longer (3.39 Å) Ba–S bond lengths. Ag1+ is bonded in a rectangular see-saw-like geometry to four equivalent S2- atoms. There are two shorter (2.50 Å) and two longer (2.83 Å) Ag–S bond lengths. Sn4+ is bonded in a tetrahedral geometry to four equivalent S2- atoms. All Sn–S bond lengths are 2.43 Å. S2- is bonded in a 5-coordinate geometry to two equivalent Ba2+, two equivalent Ag1+, and one Sn4+ atom.
