Abstract

The kinetic parameters relating to the thermal decompositions of the Co(II) and Cu(II) hydrazone complexes of general formula [ML2Br2]Cl2, whereL = anisaldehyde-Girard T cation: CH3OC6H4CH=N-NHCOCH2=\(\mathop N\limits^ + \)(CH3)3, and M=Co(II) or Cu(II), were evaluated from TG and DSC data. The thermal stabilities of the cobalt and copper complexes are discussed.

Zusammenfassung

Auf der Grundlage von TG- und DSC-Messungen wurden die kinetischen Parameter der thermischen Zersetzung von Co(II)- und Cu(II)-hydrazonkomplexen der allgemeinen Formel [ML2Br2]Cl2 mitL = Anisaldehyd-Girard T-Kation:

$$CH_3 OC_6 H_4 CH = N---NHCOCH_2 = \mathop N\limits^ + (CH_3 )_3 $$

, undM=Co(II) oder Cu(II), bestimmt. Es wurde weiterhin die thermische Stabilität dieser Komplexe beschrieben.
