Abstract
A number of trinuclear mono(carboxylato)mono(β-diketonato) complexes of nickel(II) have been synthesized by the transacylation reactions of anhydrous nickel acetate first with higher carboxylic (palmitic, stearic and behemic) acids and then with β -diketones (acetylacetone, benzoylacetone and dibenzoyl-methane) in equimolar ratios in refluxing toluene. Elemental analyses, infrared and electronic spectra, magnetic susceptibility measurements and ebullioscopic molecular weight determinations of all the above mixed ligand complexes have been carried out to throw light on the structure of these derivatives.
