Experimental Properties:The electronic absorption spectra of the Cu(II), Ni(II) and Co(II) chelates of the Schiff bases synthesized from 5-bromo-salicylaldehyde and sulfamethoxypyridazine, sulfamethizole and sulfafurazole (sulfisoxazole) were studied in dimethyl sulfoxide solution. All the chelates showed an intense charge transfer absorption band at the blue end of the visible region. The stereochemical characteristics of the chelates were illustrated by means of the absorptions caused by the d-d transitions. The Ni(II) and Co(II) chelates are 6 coordinated in all cases.|The Cu(II), Co(II) and Ni(II) chelates of the Schiff bases formed from 5-bromo-salicylaldehyde and sulfamethizole, sulfamethoxypyridazine and sulfafurazole(sulfisoxazole) were synthesized and an atomic absorption spectrometric method for the determination of the metal content of the chelates is described. The stoichiometry was found to be 1:1 for all compounds. The metal content determined by the described method agreed with theoretical values. Structure analysis by infrared spectrometry and x-ray diffraction is also included. Thermostability of these Schiff bases was investigated using a thermogravimetric method. Decomposition began at 200-290 °C for the Schiff bases, while chelates began to decompose at 60-120 °C. Stable oxides were formed by all chelated at 530-800 °C. The orders and the activation energies of some decomposition reactions were calculated for the chelates on the basis of the thermograms.|The formation and stability of copper, cobalt and nickel chelates of the Schiff bases synthesized from the 5-bromo derivatives of salicylaldehyde, sulfamethoxypyridazine, sulfamethizole and sulfisoxazole (sulfafurazole) were studied in an absolute ethanol-acetone (70:30 v/v) solution.|Hydroxyl radical reaction rate constant = 2.39X10-11 cu cm/molec-sec at 25 °C (est)
