Solvent Extraction Studies On Zn(ii) And Cd(ii) Complexes Of 1,5-dimethyl-2-phenyl-4[(e)-(2,3,4- Trihydroxyphenyl)]diazenyl-1,2-dihydroxyl-3hpyrazol-3-one.

ABSTRACT The azo-ligand, 1,5-dimethyl-2-phenyl-4-[(E)-(2,3,4-trihydroxylphenyl) diazenyl]- 1,2-dihydro-3H-pyrazol-3-one (H3L) and its Zn(II) and Cd(II) complexes have been synthesized and characterized based on stoichiometric, molar conductance, electronic and infra-red spectral studies. The results showed that H3L reacted with the metals in 2:1 ratio. H3L coordination was through the hydroxyl, azo and carbonyl groups to form [Zn(H2L)2] 2+ and [Cd(H2L)2] 2+ respectively.
