The material described by BaAg2SnSe4 crystallizes in the orthorhombic I222 space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. Ag(1) is bonded in a distorted see-saw-like geometry to four equivalent Se(1) atoms. Sn(1) is bonded in a tetrahedral geometry to four equivalent Se(1) atoms. Se(1) is bonded to two equivalent Ba(1), two equivalent Ag(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing SeBa2Ag2Sn trigonal bipyramids. is represented by the CIF file [CIF]
