Abstract

Ag9Ge2O8I crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are two shorter (2.30 Å) and one longer (2.32 Å) Ag–O bond lengths. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- and two equivalent I1- atoms. Both Ag–O bond lengths are 2.16 Å. Both Ag–I bond lengths are 3.50 Å. In the third Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three O2- and one I1- atom. There are a spread of Ag–O bond distances ranging from 2.26–2.42 Å. The Ag–I bond length is 3.54 Å. In the fourth Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- and two equivalent I1- atoms. Both Ag–O bond lengths are 2.21 Å. Both Ag–I bond lengths are 3.51 Å. Ge4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.78 Å) and two longer (1.79 Å) Ge–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three Ag1+ andmore »« less
