description: Na3VH11O11IO2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two hydrogen peroxide molecules and one Na3VH11O11I sheet oriented in the (0, 1, 0) direction. In the Na3VH11O11I sheet, there are three inequivalent Na sites. In the first Na site, Na is bonded in a 5-coordinate geometry to one H and four O atoms. The Na–H bond length is 2.23 Å. There are a spread of Na–O bond distances ranging from 2.26–2.38 Å. In the second Na site, Na is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Na–O bond distances ranging from 2.16–2.82 Å. In the third Na site, Na is bonded in a 7-coordinate geometry to four H and three O atoms. There are a spread of Na–H bond distances ranging from 2.14–2.39 Å. There are a spread of Na–O bond distances ranging from 2.45–2.69 Å. V is bonded in a 3-coordinate geometry to six O atoms.
