H2(H3O2)2(H2O2)6(SbF4)4(F2)4 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of four hydrofluoric acid molecules, one hydrogen molecule, two hydrogen peroxide molecules, two water molecules, one H3O2 cluster, and two SbF4 clusters. In the H3O2 cluster, there are three inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.61 Å. In the second H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.63 Å. In the third H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.26 Å) and one longer (1.30 Å) H–O bond length. There are two inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to two H atoms. In the second O site, O is bonded in a 1-coordinate geometry to two H atoms. In each SbF4 cluster, Sb is bonded in a 2-coordinate geometry to four F atoms. There are a spread of Sb–F bond distances ranging from 1.77–2.30 Å. There are four inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Sb atom. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a single-bond geometry to one Sb atom.
