description: (Si24O43)2(O2)9 crystallizes in the monoclinic Pm space group. The structure is three-dimensional and consists of four hydrogen peroxide molecules, one water molecule, and one Si24O43 framework. In the Si24O43 framework, there are twelve inequivalent Si sites. In the first Si site, Si is bonded in a trigonal non-coplanar geometry to three O atoms. There is two shorter (1.64 Å) and one longer (1.65 Å) Si–O bond length. In the second Si site, Si is bonded to four O atoms to form corner-sharing SiO4 tetrahedra. There is three shorter (1.62 Å) and one longer (1.63 Å) Si–O bond length. In the third Si site, Si is bonded in a trigonal non-coplanar geometry to three O atoms. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. In the fourth Si site, Si is bonded to five O atoms to form SiO5 tetrahedra that share a cornercorner with one SiO4 tetrahedra and an edgeedge with one SiO5 tetrahedra.
