Gaurang Jani, Kartik Vyas, Kiran Nimavat, Judas Franco

The stability constant of complexes of metal with 8-aceto-7-hydroxy-coumarin hydrazone was determined by JobÂ’s method at Wavelength 440 and 570 nm by keeping metal:ligand ratio is 1:2. The structure elucidation have been done by elemental analysis, IR and Magnetic studies.
