Spectrophotometric Study of Ferrous(II) and Ferric(III) Metal Complexes
By G. R. Jani1, K. B. Vyas, K. S. Nimavat and Judas Franco
The stability constant of complexes of Fe(II) and Fe (III) metals with 8-aceto-7-hydroxy-coumarin hydrazone was determined by Job’s method at Wavelength 440 and 570 nm by keeping metal:ligand ratio is 1:1. The structure elucidation have been done by elemental analysis, IR spectra, conductivity and Magnetic studies.
