Abstract
This paper presents the results of the synthesis and study of the thermal decomposition of the tetraamminecopper(II) nitrate coordination complex (TACN). The morphological structure of the obtained crystals was examined using scanning electron microscopy (SEM). The crystallite sizes were analyzed with a diffractometer. The average crystallite size, calculated by the Debye-Scherrer formula for the most intense diffraction peak, was found to be 37 nm. According to thermogravimetric analysis (DTG), mass loss begins at approximately 170 °C, with the main decomposition occurring at 237 °C. Gas evolution is observed within the temperature range of 170-275 °C.
