Phosphorus oxide
(Redirected from Phosphorus oxides)
Phosphorus oxide can refer to:
- Phosphorus pentoxide (phosphorus(V) oxide, phosphoric anhydride), P2O5
- Phosphorus trioxide (phosphorus(III) oxide, phosphorous anhydride), P2O3
- Phosphorus tetroxide, P2O4
Between the commercially important P4O6 and P4O10, several other, less common oxides of phosphorus are known. Specifically, P4O7, P4O9, and P2O6 all bear structures intermediate between the endmembers:[1]
On observation it will be seen that double bonded oxygen in P4O8 at 1,2 position or 1,3 position are identical and both positions have same steric hindrance. Cycle 12341 and ABCDA are identical.
Gases:
- Phosphorus monoxide, PO
- Phosphorus dioxide, PO2
