The latter two compounds are somewhat difficult to study individually because of the equilibrium between them, although sometimes dinitrogen tetroxide can react by heterolytic fission to nitrosonium and nitrate in a medium with high dielectric constant. Nitrogen dioxide is an acrid, corrosive brown gas.
Dinitrogen pentoxide (also known as nitrogen pentoxide or nitric anhydride) is the chemical compound with the formula N 2 O 5. It is one of the binary nitrogen oxides, a family of compounds that contain only nitrogen and oxygen. It exists as colourless crystals that sublime slightly above room temperature, yielding a colorless gas. [4]

Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. [ 11 ] [ 12 ] Nitrides of heavier members from group 11 and 12 are less stable than copper nitride ( Cu 3 N ) and zinc nitride ( Zn 3 N 2 ): dry silver nitride ( Ag 3 N ) is a contact explosive which may detonate from the slightest touch, even ...
These are all very hygroscopic compounds. [4] The solid form of dinitrogen pentoxide, N 2 O 5, actually consists of nitronium and nitrate ions, so it is an ionic compound, nitronium nitrate [NO 2] + [NO 3] −, not a molecular solid. However, dinitrogen pentoxide in liquid or gaseous state is molecular and does not contain nitronium ions. [2] [5]
Interest in such complexes arises because N 2 comprises the majority of the atmosphere and because many useful compounds contain nitrogen. Biological nitrogen fixation probably occurs via the binding of N 2 to those metal centers in the enzyme nitrogenase, followed by a series of steps that involve electron transfer and protonation.

The second method is to react elemental sodium with plasma activated nitrogen on a metal surface. This synthesis can be further facilitated by introducing liquid Na-K alloy to the compound with the excess liquid removed and washed with fresh alloy. The solid is then separated from the liquid using a centrifuge.
In chemistry, cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. [1] In inorganic cyanides, the cyanide group is present as the cyanide anion − C≡N. This anion is extremely poisonous.
