Thermal stability of Ni [II] and cu [II] mixed ligand complexes derived from biologically important schiff bases, azoles and morpholine

Thermogravimetry [TG] and differential thermogravimefty [DTG] have been applied to the investigation of the thermal behavior of six mixed ligand complexes of Ni[II] and Cu[II] comprising the Schiff bases: o-hydroxyacetophenoneethanolimine [OHAE], N-salicylidene-o-iminophenol [SOP] and N-salicylidene-o-toluidine [SOT] as well as morpholine [Morph] and certain azotes. The azoles used are: 2-amino-thiazole [2-Atz], benzothiazole [Btz], 2-methylbenzothiazole [2-Mbtz], 3-methyl-2-selenoxobenzothiazole [3-Msbtz] and thiabendazole [Tbdz]. Heating the compounds first results in a release of the morpholine or the azoles. Kinetics of the decomposition reactions were studied using non-mechanistic equations

Reactivity of certain biologically important azoles and morpholine towards Ni [II] and Cu [II] complexes of O-hydroxyacetophenoneethanolimine and N-salicylidene derivatives

A number of mixed ligand complexes of Ni [II] and Cu [II] containing the Schiff bases: o-hydroxyacetophenoneethanolimine [OHAE], N-sallicylidene-o-iminophenol [SOP] and N-salicylidene-o-toluidine [SOT] as well as morpholine or the azoles: 2-aminothiazole, benzothiazole and 2-methylbenzothiazole has been prepared and characterized. The IR, UV-VIS spectra and magnetic moment measurements of the complexes were discussed
