Phosphorus pentoxide crystallizes in at least four forms or polymorphs.The most familiar one, a metastable form [1] (shown in the figure), comprises molecules of P 4 O 10.Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing [2]).
Phosphorus pentoxide (phosphorus(V) oxide, phosphoric anhydride), P 2 O 5; Phosphorus trioxide (phosphorus(III) oxide, phosphorous anhydride), P 2 O 3; Phosphorus tetroxide, P 2 O 4; Several other, less common, oxides of phosphorus, including P 4 O 7, P 4 O 9, and P 2 O 6; Gases: Phosphorus monoxide, PO; Phosphorus dioxide, PO 2
The compound can also be created in the gas phase by reacting nitrogen dioxide NO 2 or N 2 O 4 with ozone: [13] 2 NO 2 + O 3 → N 2 O 5 + O 2. However, the product catalyzes the rapid decomposition of ozone: [13] 2 O 3 + N 2 O 5 → 3 O 2 + N 2 O 5. Dinitrogen pentoxide is also formed when a mixture of oxygen and nitrogen is passed through an ...

Pentoxide may refer to: Antimony pentoxide, Sb 2 O 5; Arsenic pentoxide, As 2 O 5; Carbon pentoxide, CO 5; Dinitrogen pentoxide, N 2 O 5; Iodine pentoxide, I 2 O 5 ...
Many nitrogen compounds such as hydrogen cyanide and nitrogen-based explosives are also highly dangerous. [14] White phosphorus, an allotrope of phosphorus, is toxic, with 1 mg per kg bodyweight being a lethal dose. [12] White phosphorus usually kills humans within a week of ingestion by attacking the liver.
Arsenic pentoxide is the inorganic compound with the formula As 2 O 5. [2] This glassy, white, deliquescent solid is relatively unstable, consistent with the rarity of the As(V) oxidation state. More common, and far more important commercially, is arsenic(III) oxide (As 2 O 3 ).
