Chelating behaviour of substituted 3-arylhydrazo pentane-2,4-dione [SBHP] ligands Part VI Complexes of nickel [II] with o-,m-, p-, and 4-Me-o-sulphonic benzene hydrzo-pentane-2, 4-dione

In a previous article the composition and stability constants of the copper [II] complexes with o-, m-, p-, and 4-o-sulphonic benzenehydrazo-pentane-2, 4-dione ligands were determined. The present study deals with the determination of the composition, structure elucidation and stability constants of Ni [II] complexes with the above ligands by spectrophotometric, conductometric, and pH- metric measurements

Infrared spectroscopic investigation of divalent and tervalent metal complexes of sulphonic derivatives of phenyl-hydrazoacetylacetone

The Infrared spectra of a number of metal-sulphonic phenyl-1 hydrazoacetylacetone complexes have been recorded. The absorption frequencies of metal-nitrogen and metaloxygen bonds are assigned and their co-ordination bond lengths are calculated. The force constant of the ligandmetal bond was also calculated
