Abstract
4-(R-Phenylazo)-2-methyl quinoline derivatives form (1:1) complexes with nickel chloride, nickel acetate and copper acetate which were syntheses. The three complexes are non-electrolyte in dimethylsulfoxide (DMF). The results of electronic and magnetic measurements show that these complexes are of octahedral structures. The oxygen and nitrogen donate their lone-pair electrons to metal ion to form chelates with formula [MLRm.nH2O]. The relative stabilities of the complexes have been calculated from TG curve using Coats-Redfern and Ozawa methods.
Highlights
Azo compounds have been the subject of numerous spectral studies aimed at their identification or structural elucidation [1,2,3,4]
The calculated values of the suggested structural formula of the chelates are in good agreement with the values obtained from elemental analysis data (Table 1) dimethylsulfoxide was used as solvent at 25 ̊C to calculate the molar conductivities of the chelates which was found to be 13.25 - 20.2017 Ohm−1, these value are in non-electrolytic region which mean these chelates are of nonelectrolytic nature [8,9]
The water of hydration or coordination appear in the IR spectra of all metal chelates causes difficulty in drawing conclusions from the ν(OH) band for the hydroxyl groups of the free ligand, which would overlap
Summary
Azo compounds have been the subject of numerous spectral studies aimed at their identification or structural elucidation [1,2,3,4]. Interest in azo compounds stems from their ability to form metal chelates with metal ions [5,6]. The synthesis and characterization of new metal chelate derived from the kinaldine azo dye have been reported [7], but no report concerning the solid-state kinetics of such complexes has been published. The aims of the present investigation are the preparation and elucidation of the geometrical structure of the metal chelates formed between divalent transition metal ions with different counter ions of acetate or chloride. The kinetics of the thermal decomposition of the azo dye complexes was studied using dynamic thermogravimetric techniques
