O2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of four trioxidane molecules. There are two inequivalent O sites. In the first O site, O(1,2,3,5,6,8) is bonded in a single-bond geometry to one O(9,10,11,12) atom. In the second O site, O(9,10,11,12) is bonded in a bent 120 degrees geometry to two equivalent O(4,7) atoms.

In the first O site, O(1,2,3,5,6,8) is bonded in a single-bond geometry to one O(9,10,11,12) atom. The O(1,2,3,5,6,8)-O(9,10,11,12) bond length is 1.28 Å. In the second O site, O(9,10,11,12) is bonded in a bent 120 degrees geometry to two equivalent O(4,7) atoms. There is one shorter (1.28 Å) and one longer (1.29 Å) O(9,10,11,12)-O(4,7) bond length.
