AgBiO2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgBiO2 cluster. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one O(1) and one O(3) atom. The Ag(1)-O(1) bond length is 1.17 Å. The Ag(1)-O(3) bond length is 1.17 Å. In the second Ag site, Ag(2) is bonded in a linear geometry to one O(2) and one O(4) atom. The Ag(2)-O(2) bond length is 1.17 Å. The Ag(2)-O(4) bond length is 1.17 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a bent 150 degrees geometry to one O(2) and one O(3) atom. The Bi(1)-O(2) bond length is 1.88 Å. The Bi(1)-O(3) bond length is 1.79 Å. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one O(1) atom. The Bi(2)-O(1) bond length is 1.79 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Ag(1) and one Bi(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ag(2) and one Bi(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Ag(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Ag(2) atom.
