Synthesis of Cadmium Nitride Cd 3 N 2 by Thermolysis of Cadmium Azide Cd(N 3 ) 2 and Crystal Structure Determination from X‐ray Powder Diffraction Data Cadmium nitride Cd 3 N 2 was obtained by thermolysis of cadmium azide Cd(N 3 ) 2 at 2·10 −6 mbar and 210 °C. It was obtained as a black, crystalline powder which becomes brown in air due to formation of cadmium amide Cd(NH 2 ) 2 . The crystal structure of Cd 3 N 2 was determined from X‐ray powder diffraction data and refined by the Rietveld method ( $Ia{\bar 3}$ , a = 10.829(9) Å, V = 1270(3) Å 3 , Z = 16, R(F 2 ) = 0.1196). Cd 3 N 2 crystallizes in the anti‐bixbyite structure type and is isotypic to Ca 3 N 2 .
