Solution Studies and Biological Activity of Some Bivalent Metal Complexes with Schiff Bases Derived From 3-Phenyl Salicylaldehyde

摘要

Potentiometric studies have been carried out on metal complexes of Cu~(2+),Ni(2+),Co(2+),Zn(2+), Cd(2+) and Mg(2+) with N-[3-phenyl salicylidene]-4- methoxy aniline, N-[3-phenyl salicylidene]-2,5-dimethoxy and iline ,N-[3-phenyl salicylidene]-2,5-dimethoxy-4-nitroaniline. The stability constants of the regents and their bivalent metal ion chelates have been determined by Calvin-Bjerrum pH titration technique as adopted by lrving and Rossotti at 303 K and at an ionic strength of 0.1 M in 75:25(v/v) dioxane-water medium. Since the above reagents investigated by us are good chelating agents they were also screened for their antibacterial and anticoagulant activity.
