Abstract

AgTl3I5 crystallizes in the hexagonal P-62c space group. The structure is three-dimensional. Ag2+ is bonded to six I1- atoms to form face-sharing AgI6 octahedra. There are three shorter (3.10 Å) and three longer (3.14 Å) Ag–I bond lengths. There are six inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Tl–I bond distances ranging from 3.36–4.25 Å. In the second Tl1+ site, Tl1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Tl–I bond distances ranging from 3.36–4.25 Å. In the third Tl1+ site, Tl1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Tl–I bond distances ranging from 3.36–4.25 Å.
