diphosphonic acid

Guidance literature:: In neat (no solvent); cryst. H4P2O6 is converted at ambient temp. during a few days for 70% toisosubphosphoric acid by isomerisation, the rest is converted by oxido- reduction into H4P2O7 and H2(H2P2O5); the same reaction proceeds by heating at 70 to 95°C;; chromy., raman spectroscopy;;
