1.Eight new chelates have been prepared from uranyl nitrate and Schiff bases, and all of them contain two molecule$ of nitric acid to satisfy coordination number of uranium which is eight in these complexes.2.Results of thermogravimetric analysis of these complexes show that the two nitric acid molecules are in the inner sphere and coordinated directly to uranium.3.Molar conductivities of the complexes in methyl alcohol and pyridine solutions have been determined and the results indicate that they resemble Ⅱ-Ⅰ type electrolytes in conductance.4.Solubilities of the complexes in ethyl alcohol at 250C have also been determined.
