IR, X-ray diffraction and thermogravimetric studies were used to illustrate the structure of neodymi-um caprylate, laurate and myristate in solid state. IR results reveals that the fatty acids exists with dimeric structure through intermolecular hydrogen bonding and neodymium caprylate, laurate and myristate were ionic in nature. The X-ray diffraction measurement confirms that these soaps possess double layer structure with a molecular axis slightly inclined to the basal plane. The results of thermogravimetric analysis reveals that the thermal decomposition reaction was kinetically of zero order and energy of activation for the decomposition process lies in the range of 24-32 KJmol-1.
