Complex of Fe(III) with isonicotinohydroxamic acid (INHA) has been investigated by using spectrophotometric method. Fe(III) in aqueous solution revealed the sole formation of the 1:3 complexes at equilibrium. The spectra and magnetic studies of the isolated complex indicated octahedral coordination. The bonding mode proposed for the Fe(III) hydroxamate complex is N-bonding mode.The complex is biologically active against Staphyloccus.aureus, Escherichia-coli, Salmonella-typhyllium, Klebsiella ,-heamolytic Streptocococcus, Pseudomonias, Corrynebacterium and Neisseria.
Key words: Hydroxamic acid, Fe(III) complex, N-bonding mode, microorganism and octahedral coordination.
