"Ligand Field And Counter Anion Effects on the Thermal Stability of Copper(II) Complexes of 1,2-Di(imino- 4´-antipyrinyl)ethane and 4-N-(4´-antipyrylmethylidene) aminoantipyrine";
Journal of Chemistry and Applied Chemical Engineering, 1 (2018), 2; S. 1 - 8.

A comparative thermolytic investigation on copper(II) complexes
with two antipyrine Schiff base derivatives, namely 1,2-Di(imino-
4´-antipyrinyl)ethane (GA) and 4-N-(4´-antipyrylmethylidene)
aminoantipyrine (AA), with different counter anions like perchlorate,
nitrate, chloride, and bromide has been done by thermogravimetric
and derivative thermogravimetric analysis. The present investigation
reveals that the counter anions and the ligand field play a big role on
the thermal stability of the copper (II) complexes of both Schiff base
derivatives. For the present complexes, the thermal decomposition
mechanism has been investigated according to Satava, which
follows a `random nucleation with one nucleus on each particle, i.e.
the Mampel model´.
