Did you know?
A phosphite anion or phosphite in inorganic chemistry usually refers to [HPO3] but includes [H2PO3] ([HPO2(OH)] ). These anions are the conjugate bases of phosphorous acid (H3PO3). The corresponding salts, e.g. sodium phosphite (Na2HPO3) are reducing in character. See more The IUPAC recommended name for phosphorous acid is phosphonic acid. Correspondingly, the IUPAC-recommended name for the HPO 3 ion is phosphonate.

They contain the ion H 2P 2O 5, which can be formulated [HP(O)2O−P(O)2H] .

The latter result in the two-electron oxidation of the phosphorus atom from +III to +V, and are accompanied by a strong geometric distortion of the NNN pincer ligand. By contrast, cooperative activation of E–H (HCl, HBcat, HOMe) bonds proceeds with retention of the phosphorus redox state.
