The two known phases of germanium nitride (Ge 3 N 4) have hexagonal and trigonal
symmetries and consist of three-dimensional networks of corner-connected Ge–N
tetrahedra. A new cubic spinel phase (space-group Fd3m, a 0= 8.3 Å, Z= 8, ρ= 6.36 g/cm 3)
containing Ge–N octahedra and tetrahedra in a 2: 1 ratio was synthesized from elemental
germanium and molecular nitrogen starting materials in a laser-heated diamond-anvil cell
above 14 GPa. This phase is isostructural to the recently discovered cubic spinel phase of Si …
