• Resumen

  • Azomethine ligands with electron-withdrawing groups such as bis{N,N′-(2-ethoxycarbonyl-3-oxo-but-1-en(1)yl)-1,2-diaminobenzene (H2L1) or N-(2-ethoxycarbonyl-3-oxo-but-1-en(1)yl)-2-aminophenol (H2L2) react with uranyl nitrate under deprotonation and formation of chelate complexes. The composition of the products can be controlled by the reaction conditions and the denticity of the ligands. Structure determinations have been performed on [NEt3H][UO2(L1)(OMe)], [UO2(L1)(DMSO)] and [NEt3H]2[{UO2(L2)}3(μ3-O)].
