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.
