The crystal structure and thermal analysis of ZTO and its solvent adducts

4,4-azo-bis(1,2,4-triazol-5-one) (ZTO) and its solvent adducts have been reported, and the single crystal X-ray measurements indicated that the ZTO crystals appeared as a monoclinic system with space group P2(1)/c, while ZTO·2H 2 O and ZTO·2DMF displayed as monoclinic with space group P2(1)/n and tr...

Zusammenfassung:4,4-azo-bis(1,2,4-triazol-5-one) (ZTO) and its solvent adducts have been reported, and the single crystal X-ray measurements indicated that the ZTO crystals appeared as a monoclinic system with space group P2(1)/c, while ZTO·2H 2 O and ZTO·2DMF displayed as monoclinic with space group P2(1)/n and triclinic with space group Pī, respectively. In addition, the thermal decomposition process of the three crystals was studied by thermogravimetric differential analysis (TG-DTA), and the result showed that only one exothermic peak was found in each case of ZTO, ZTO·2H 2 O, and ZTO·2DMF, and the peak temperature ( T p ) are observed at 292.36, 291.82, and 272.73 °C, respectively.
