Germanium(IV) nitride is an inorganic compound with the chemical formula Ge₃N₄. It can be produced through the reaction of germanium and ammonia:^[1]

3 Ge + 4 NH₃ → Ge₃N₄ + 6 H₂

Structure

In its pure state, germanium(IV) nitride is a colorless, inert solid that crystallizes in many polymorphs, of which the most stable is the trigonal β-form (space group P31c). In this structure, the germanium atoms are tetrahedrally coordinated while the nitrogen atoms are trigonal planar.^[2] The γ-form, which forms under high pressure, has a spinel structure.^[3]
