There are a spread of Ag–O bond distances ranging from 2.38–2.51 Å. The Ag–I bond length is 2.74 Å. In the fourth Ag1+ site, Ag1+ is bonded in a 2-coordinate geometry to two O2- and two I1- atoms. There are one shorter (2.35 Å) and one longer (2.41 Å) Ag–O bond lengths. There are one shorter (2.95 Å) and one longer (2.98 Å) Ag–I bond lengths. In the fifth Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three O2- and two equivalent I1- atoms. There are one shorter (2.35 Å) and two longer (2.42 Å) Ag–O bond lengths. There are one shorter (2.86 Å) and one longer (3.57 Å) Ag–I bond lengths. In the sixth Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to two O2- and two I1- atoms. There are one shorter (2.38 Å) and one longer (2.39 Å) Ag–O bond lengths. Both Ag–I bond lengths are 2.83 Å. In the seventh Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.29–2.77 Å. In the eighth Ag1+ site, Ag1+ is bonded in a distorted water-like geometry to two O2- and three I1- atoms. There are one shorter (2.36 Å) and one longer (2.37 Å) Ag–O bond lengths. There are a spread of Ag–I bond distances ranging from 3.08–3.28 Å. There are three inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share a cornercorner with one AgO4 trigonal pyramid. There is one shorter (1.72 Å) and three longer (1.74 Å) As–O bond length. In the second As5+ site, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.73 Å) and two longer (1.74 Å) As–O bond length. In the third As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with three equivalent AgO4 trigonal pyramids. There are a spread of As–O bond distances ranging from 1.73–1.75 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to three Ag1+ and one As5+ atom to form a mixture of distorted edge and corner-sharing OAg3As tetrahedra. In the second O2- site, O2- is bonded to three Ag1+ and one As5+ atom to form distorted corner-sharing OAg3As tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag1+, one As5+, and one I1- atom. The O–I bond length is 3.63 Å. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ag1+ and one As5+ atom. In the fifth O2- site, O2- is bonded in a distorted tetrahedral geometry to three Ag1+ and one As5+ atom. In the sixth O2- site, O2- is bonded to three Ag1+ and one As5+ atom to form distorted corner-sharing OAg3As tetrahedra. In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ag1+ and one As5+ atom. In the eighth O2- site, O2- is bonded to three Ag1+ and one As5+ atom to form a mixture of distorted edge and corner-sharing OAg3As tetrahedra. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one As5+ atom. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in a 7-coordinate geometry to two equivalent Ag1+ atoms. In the second I1- site, I1- is bonded in a 5-coordinate geometry to seven Ag1+ and one O2- atom. In the third I1- site, I1- is bonded in a 6-coordinate geometry to six Ag1+ atoms. In the fourth I1- site, I1- is bonded in a 6-coordinate geometry to six Ag1+ atoms.
