The structure described by AgO8I3 crystallizes in the orthorhombic Pnc2 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(3) and two equivalent O(5) atoms. In the second Ag site, Ag(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(5) atoms. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Ag(1), one Ag(2), and one I(3) atom. In the second O site, O(6) is bonded in a single-bond geometry to one I(3) atom. In the third O site, O(7) is bonded in a bent 120 degrees geometry to one I(3) and one I(4) atom. In the fourth O site, O(8) is bonded in a distorted single-bond geometry to one I(1) and one I(4) atom. In the fifth O site, O(1) is bonded in a water-like geometry to one Ag(2) and one I(1) atom. In the sixth O site, O(2) is bonded in a single-bond geometry to one I(1) atom. In the seventh O site, O(3) is bonded in a trigonal planar geometry to one Ag(1), one I(1), and one I(2) atom. In the eighth O site, O(4) is bonded in a distorted single-bond geometry to one I(2) and one I(3) atom. There are four inequivalent I sites. In the first I site, I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), one O(3), and one O(8) atom. In the second I site, I(2) is bonded in a see-saw-like geometry to two equivalent O(3) and two equivalent O(4) atoms. In the third I site, I(3) is bonded in a 3-coordinate geometry to one O(4), one O(5), one O(6), and one O(7) atom. In the fourth I site, I(4) is bonded in a see-saw-like geometry to two equivalent O(7) and two equivalent O(8) atoms. is represented by the CIF card [CIF]
