Role of anions on biologically active complexes of Cobalt [II] and Nickel [II] with pyrimidine-derived Schiff bases

ABSTRACT

Biologically active complexes cobalt and nickel with pyrimidine - derived Shiff bases having the same metal atom but different anions such as chloride, sulphate, nitrate, oxalate and acetate have been synthesized. In order to evaluate the effect of anions on their bioability, they have been screened against bacterial species Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae
