Synthesis and characterization of hydroxycarboxylato complexes of nickel(II)

Abstract

Acetate groups of anhydrous nickel(II) acetate have been substituted with some higher carboxylic acids and hydroxycarboxylic acids in toluene under reflux and the products Ni(OOCR)(OOCR'), Ni(OOCR) (OOCR") and Ni(OOCR)(OOCR"') [where R=C₁₃H₂₇, C₁₇H₃₅ or C₂₁H₄₃ and R'=C₆H₄OH,

Rʹʹ = C₆H₅CH(OH) and R'" = (C₆H₅)₂C(OH)] obtained have been characterized by elemental analyses, electronic and IR spectra and conductivity measurements. An octahedral environment around nickel(II) ion is suggested and the molecular weight determinations confirm the dinuclear nature of these complexes.
