A novel copper(II) coordination compound was synthesized using azodicarbonamide (ADC) as ligand (Cu II ‐ADC). The structural, morphological, and optical properties of the synthesized material are investigated using X‐ray diffraction, field emission scanning electron microscopy, Fourier transform infrared, and diffuse reflectance spectroscopy. Evaluation of the obtained results indicates that ADC coordinated to copper ions. Ammonium nitrate (AN) is an affordable oxidant, which is widely used in gas generators. Since AN shows crystal structure transformation in ambience temperature accompanied by a change in volume, its application is limited without phase stabilization. For phase stabilization of AN, AN/Cu II ‐ADC composite is prepared and its phase transitions is studied using differential scanning calorimetry. The results indicate that AN IV ↔AN III phase transition can be eliminated by hydrogen bonding between AN and Cu II ‐ADC.
