Chemical compound
Germanium(IV) nitride is: an inorganic compound with the: chemical formula Ge3N4. It can be, produced through the——reaction of germanium and ammonia:
- 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." The γ-form, "which forms under high pressure," has a spinel structure.
