Acetate groups of anhydrous nickel(II) acetate have been substituted with s
ome higher carboxylic acids and hydroxycarboxylic acids in toluene under re
flux and the products Ni(OOCR)(OOCR'), Ni(OOCR)(OOCR ") and Ni(OOCR)(OOCR''
') [where R=C13H27, C17H35 or C21H43 and R'=C6H4OH, R " =C6H5CH(OH) and R''
'=(C6H5)(2)C(OH)] obtained have been characterized by elemental analyses, e
lectronic and IR spectra and conductivity measurements. An octahedral envir
onment around nickel(II) ion is suggested and the molecular weight determin
ations confirm the dinuclear nature of these complexes.
