A red‐brown zirconium nitride was prepared by ammonolysis of ZrCl 4 . Chemical analysis leads to a composition of Zr 3 N 4 . It is not possible to distinguish between the space groups Pnam and Pna2 1 in the case of Zr 3 N 4 using powder methods. The lattice constants are: a = 972.94(5) pm, b = 1081.75(6) pm, c = 328.10(1) pm (Z = 4). X‐ray powder diffraction data were used for structure refinement. The high temperature behavior was investigated with in situ XRD methods. Zr 3 N 4 decomposes into ZrN and nitrogen gas at temperatures above 800°C.
