The Complexation of Some Transition Metals by Acetoacetanilidehydrazo Ligands “Stability Constants”

Acid dissociation constants of acetoacetanilide abbreviated (AAA); Orthocarboxy-phenylhydrazoacetoacetanilide (o-CPHAAA); and orthocarboxy-phenylhydrazo-parachloro-acetoacetanilide (o-CPH-p-Cl-AAA) and chelate stability constants of the corresponding anions with Cu⁺², Ni⁺², CO⁺², Zn⁺², Mn⁺², and Cd⁺² ions are reported. The infra-red spectra of o-CPHAAA and o-CPH-p-Cl-AAA ligands and their chelates for copper and nickel are discussed.
