Abstract

Rb3AgSn3Se8 crystallizes in the tetragonal P4/nbm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.51 Å) and four longer (3.72 Å) Rb–Se bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. All Rb–Se bond lengths are 3.72 Å. Ag1+ is bonded to four equivalent Se2- atoms to form distorted AgSe4 tetrahedra that share edges with two equivalent SnSe4 tetrahedra. All Ag–Se bond lengths are 2.83 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to four Se2- atoms to form SnSe4 tetrahedra that share an edgeedge with one AgSe4 tetrahedra and an edgeedge with one SnSe4 tetrahedra. There are two shorter (2.52 Å) and two longer (2.67 Å) Sn–Se bond lengths. In the second Sn4+ site, Sn4+ is bonded to four equivalent Se2- atoms to form edge-sharing SnSe4 tetrahedra. All Sn–Se bond lengths are 2.58 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 6-coordinate geometry to four Rb1+, one Ag1+, andmore »« less
