Preparation Characterisation and Light Absorption Spectrophotometry of Copper (II) and Nickel(lI) Complexes of Some Fluorinated Tetradentate Ketoamine Schiff Bases

Copper(II) and nickel(II) complexes of tetradentate ketoamine Schiff bases bis(tri­Ouoroacetylmesityloxide) ethylenediimine (H2F3AM2en), bis(triOuoroacetylmesityloxide) propylenediimine (H2F3AM2pn), bis (triOuoroacetylmesityloxide) d-stilbenediimine (dl­H2F3AM2S) and bis(triOuoroacetylmestiyloxide) meso-stilbenediimine (meso- H2F3AM2S) are prepared and IR, lH_NMR and mass spectra of the reagents are recorded. Ultraviolet and visible spectra of the reagents and metal complexes are recorded in methanol, acetone, chloroform and n-hexane and possible assignment of the different bands is suggested.
