Materials Data on BaAg2SnSe4 by Materials Project
BaAg2SnSe4 crystallizes in the orthorhombic I222 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are four shorter (3.48 Å) and four longer (3.50 Å) Ba–Se bond lengths. Ag1+ is bonded in a distorted see-saw-like geometry to four equivalent Se2- atoms. There are two shorter (2.59 Å) and two longer (2.99 Å) Ag–Se bond lengths. Sn4+ is bonded in a tetrahedral geometry to four equivalent Se2- atoms. All Sn–Se bond lengths are 2.58 Å. Se2- is bonded to two equivalent Ba2+, two equivalent Ag1+, and one Sn4+ atom to form a mixture of distorted corner and edge-sharing SeBa2Ag2Sn trigonal bipyramids.
