In the second V5+ site, V5+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.66–2.30 Å. There are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.45–2.69 Å.

In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two V5+ atoms. In the eighth O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Ag1+ and two I5+ atoms. There are one shorter (1.85 Å) and one longer (2.83 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ag1+ and two I5+ atoms. There are one shorter (1.87 Å) and one longer (2.63 Å) O–I bond lengths. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ag1+ and one I5+ atom. The O–I bond length is 1.85 Å. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to two Ag1+ and one I5+ atom. The O–I bond length is 1.82 Å. In the thirteenth O2- site, O2- is bonded in a 3-coordinate geometry to one V5+ and two equivalent I5+ atoms. There are one shorter (1.86 Å) and one longer (2.55 Å) O–I bond lengths. In the fourteenth O2- site, O2- is bonded in a 2-coordinate geometry to one V5+ and one I5+ atom. The O–I bond length is 1.92 Å. In the fifteenth O2- site, O2- is bonded in a 2-coordinate geometry to one V5+ and one I5+ atom. The O–I bond length is 1.89 Å. In the sixteenth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one I5+ atom. The O–I bond length is 1.87 Å. There are four inequivalent I5+ sites.
