In chemistry, pernitrides are compounds containing the pernitride group, . Pernitride is isoelectronic to peroxide (), from which the name is derived.
Pernitrides for each of the platinum group elements in their +4 oxidation state (M = Pt, Ir, Os, Pd, Rh, Ru) have been obtained via direct combination of the elements at high temperature and pressure using a laser heated diamond anvil cell. Titanium(IV) pernitride can likewise be obtained by combining titanium(III) nitride () with molecular nitrogen. All these pernitrides are recoverable (kinetically persistent) at ambient temperature and pressure with the exception of , which was inferred to decompose below 13 GPa.
Pernitrides are related to hydrazine and inorganic hydrazides, from which they may be formally derived via deprotonation. A gallium pernitride complex has been synthesized via thermolysis of the corresponding hydrazide .
