In chemistry, pernitrides are compounds containing the pernitride group, N2−−N2−. Pernitride is isoelectronic to peroxide (O−−O−), from which the name is derived.[1]
Transition metal pernitrides
[edit]Pernitrides MN2 for each of the platinum group elements in their +4 oxidation state (M = Pt,[2] Ir,[2] Os,[3] Pd,[4] Rh,[5] Ru[6]) have been obtained via direct combination of the elements at high temperature and pressure using a laser heated diamond anvil cell. Titanium(IV) pernitride TiN2 can likewise be obtained by combining titanium(III) nitride (TiN) with molecular nitrogen.[7] All these pernitrides are recoverable (kinetically persistent) at ambient temperature and pressure with the exception of PdN2, which was inferred to decompose below 13 GPa.[4][7][8]
Pernitride complexes
[edit]Pernitrides are related to hydrazine and inorganic hydrazides, from which they may be formally derived via deprotonation. A gallium pernitride complex [(GaMe)4(GaMe2)4(N2)(NH−NMe)4] has been synthesized via thermolysis of the corresponding hydrazide [(GaMe2)4(NH−NMe)(NH−NHMe)2].[9][10]
