[Co(Gly)_2(DABT)]·2H_2O配合物的红外光谱及热稳定性的研究

The Study of IR Spectrum and Thermal Stability of [Co(Gly)_2(DABT)]·2H_2O

研究了标题配合物的红外光谱和热稳定性。红外光谱分析结果表明,配位的2,2′-二氨基-4,4′-联噻唑的噻唑环和氨基上的两个氮的异构化交换引起的骨架振动由1342cm-1红移至1298cm-1。热分析结果表明,配合物在135℃附近先失去两个结晶水,在314℃附近甘氨酸羧基中C—O(配位)键断裂,配合物失去两个甘氨酸阴离子部分,配合物的剩余部分则在320℃以后继续以缓慢的速率进行放热分解。

The IR spectrum and thermal stability of the title complex have been studied. The results indicated that the absorption frequency of C-N bond between thiazole ring and amino of 2,2＇- diamino-4,4＇-bithiazole shifted from 1342cm^-1 to 1298cm^-1 The complex lost two lattice waters at 135℃ firstly, and then lost two glycine anions at 314℃ with the bond breaking of C-O （coordinated） of carboxyl. Finally, residual substances decomposed slowly with radiative effect after 320 ℃.
