Sodium nitride is the inorganic compound with the chemical formula Na₃N. In contrast to lithium nitride and some other nitrides, sodium nitride is an extremely unstable alkali metal nitride. It can be generated by combining atomic beams of sodium and nitrogen deposited onto a low-temperature sapphire substrate.^[1] It readily decomposes into its elements:

{\ce {2 Na3N -> 6 Na + N2}}
