Metal carboxylate was prepared by metathesis of potassium decanoate with terbium nitrate aqueous solution. Thermal study reveals that metal carboxylate breakdown processes are kinetically of zero order, with activation energies ranging from 11 to 13 kcal mol-1. Infrared red spectra of terbium decanoate and decanoic acid indicated that fatty acids have a dimeric structure due to hydrogen bonding between two molecules of carboxylic acid, whereas metal to oxygen bond in terbium decanoate is ionic in nature. X-ray diffraction confirms the double layer structure of terbium decanoate and zig zag chains of fatty acid radical constituent of carboxylate molecule extend straight forward on both side of each basal plane, with the molecular axis slightly inclined to the basal plane.
