The recently published synthesis of the presumably daltonide phase InFe 3 N has been re‐investigated. A two‐step ammonolysis reaction gives access to the phase‐pure berthollide In x Fe 4– x N (0 ≤ x ≤ 0.8), which adopts a perovskite‐like structure in space group Pm $\bar{3}$ m . There is a Vegard‐type behavior of the lattice parameter over the entire compositional range, and a similar trend is found for the magnetic saturation moment, which decreases while the indium content increases. Susceptibility measurements and hysteretic loops (10 K, 290 K) evidence that In 0.8 Fe 3.2 N is a ferromagnetic nitride.
