Arsenide nitrides or nitride arsenides are compounds containing anions composed of nitride (N3−) and arsenide (As3−). They can be considered as mixed anion compounds or mixed pnictide compounds. Related compounds include the arsenide phosphides, germanide arsenides, arsenide carbides, and phosphide nitrides.
Arsenide and nitride are quite different in size, so alloys are challenging to produce. They can be produced by heating an arsenide compound with a nitride, under pressure so that nitrogen does not escape.
