There are a spread of Ag–Br bond distances ranging from 2.74–2.87 Å. In the eighth Ag+1.22+ site, Ag+1.22+ is bonded in a 2-coordinate geometry to four Ag+1.22+, three Te2-, and one Br1- atom. There are a spread of Ag–Te bond distances ranging from 2.86–3.26 Å. The Ag–Br bond length is 2.99 Å. In the ninth Ag+1.22+ site, Ag+1.22+ is bonded in a 1-coordinate geometry to two Te2- and three Br1- atoms. There are one shorter (2.78 Å) and one longer (2.88 Å) Ag–Te bond lengths. There are one shorter (2.73 Å) and two longer (3.19 Å) Ag–Br bond lengths. There are four inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to six Ag+1.22+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to five Ag+1.22+ atoms. In the third Te2- site, Te2- is bonded in a 6-coordinate geometry to six Ag+1.22+ atoms. In the fourth Te2- site, Te2- is bonded in a 6-coordinate geometry to six Ag+1.22+ atoms. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted rectangular see-saw-like geometry to four Ag+1.22+ atoms. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to five Ag+1.22+ atoms. In the third Br1- site, Br1- is bonded in a 5-coordinate geometry to five Ag+1.22+ atoms.« less
