Pentaoxidane is an inorganic compound of hydrogen and oxygen with the chemical formula H2O5.[1] This is one of the most unstable hydrogen polyoxides.[2][3][4]

Synthesis

[edit]
  • The compound is prepared as a byproduct of trioxidane production.[5]
  • H2O5 has also been synthesized by reaction among peroxy radicals at low temperature.[6]
