Synthesis, characterization and total phenolic content of Ni(ii) and Cr(iii) hydroxamic acids complexes / Suhainiza Bari

Four complexes of Hydroxamic acid ligands, 2-pyridinehydroxamic acid and salicylhydroxamic acid with metal Ni(II) and Cr(III) have been prepared in ratio 2:1 (hydroxamic acids : metal salt). New hydroxamic acid complexes bis(salicylhydroximato)Nickelate(II) derived from salicylhydroxamic acid and Ni...
