The controlled reaction of concentrated H 2 O 2 with oleum affords H 2 SO 5 /H 2 SO 4 mixtures from which single crystals of H 2 SO 5 ( 1 ) precipitate. The X‐ray crystal structure analysis contradicts the postulates based on vibrational spectroscopy and shows that 1 occurs as peroxoacid without intramolecular hydrogen bonds (picture right), but is linked in a layer type structure by strong intermolecular OH … O hydrogen bonds.
