    en.wikipedia.org/wiki/Phosphorus_tetroxide

    Diphosphorus tetroxide, or phosphorus tetroxide is an inorganic compound of phosphorus and oxygen. It has the empirical chemical formula P 2 O 4 . Solid phosphorus tetroxide (also referred to as phosphorus(III,V)-oxide) consists of variable mixtures of the mixed-valence oxides P 4 O 7 , P 4 O 8 and P 4 O 9 .

    The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and ⁠ n + 2 / 2 ⁠. Pyrophosphate anion. Trimethyl ...

    en.wikipedia.org/wiki/Phosphoryl_group

    A phosphoryl group is a trivalent >P(=O)− group, consisting of a phosphorus atom (symbol P) and an oxygen atom (symbol O), where the three free valencies are on the phosphorus atom. While commonly depicted as possessing a double bond (P=O) the bonding is in fact non-classical. [1]

  6. Oxyphosphides - Wikipedia

    en.wikipedia.org/wiki/Oxyphosphides

    Oxyphosphides are chemical compounds formally containing the group PO, with one phosphorus and one oxygen atom. The phosphorus and oxygen are not bound together as in phosphates or phosphine oxides, instead they are bound separately to the cations (metals), and could be considered as a mixed phosphide-oxide compound. So a compound with O m P n ...

  7. Allotropes of phosphorus - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_phosphorus

    Phosphorus reacts with oxygen, usually forming two oxides depending on the amount of available oxygen: P 4 O 6 (phosphorus trioxide) when reacted with a limited supply of oxygen, and P 4 O 10 when reacted with excess oxygen. On rare occasions, P 4 O 7, P 4 O 8, and P 4 O 9 are also formed, but in small amounts.

    In chemistry, phosphorus oxoacid (or phosphorus acid) is a generic name for any acid whose molecule consists of atoms of phosphorus, oxygen, and hydrogen. [1] There is a potentially infinite number of such compounds. Some of them are unstable and have not been isolated, but the derived anions and organic groups are present in stable salts and ...
