Beryllium nitride Be3N2 is a nitride of beryllium. It can be prepared from the elements at high temperature (1100–1500 °C) unlike Beryllium azide or BeN6it decomposes in vacuum into beryllium and nitrogen. It is readily hydrolysed forming beryllium hydroxide and ammonia. It has two polymorphic forms cubic α-Be3N2 with a defect anti-fluorite structure and hexagonal β-Be3N2. It reacts with silicon nitride Si3N4 in a stream of ammonia at 1800–1900°C to form BeSiN2.
