The conditions of the formation of rare earth element m-nitrobenzoates were studied and their quantitative composition and solubilities in water and benzene at 298 K were determined (their solubilities are in the orders of 1E-3 mol/dm3 and 1E-4 mol/dm3, respectively).From the values of solubilities in water the solubility products were established (they are in the orders of 1E-10 mol4/dm12).The IR and X-ray spectra for the prepared complexes and the dehydrated rare earth m-nitrobenzoates were recorded.All obtained complexes were found to be crystalline compounds.The conditions of thermal decomposition for complexes were also studied.It was found that on heating above 573 K the complexes decompose explosively and undergo a melting process at the same time.Therefore the thermal decomposition was carried out in the temperature range 273 - 573 K.The obtained results show that during dehydration process no transformation of the nitro group to nitrito occurs. - Keywords: Complexes; Rare earth elements; Lanthanides
