Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this thesis, N-substituted diethanolamine ligands have been employed in the syntheses of heterometallic FeIII-LnIII clusters. The reactions of a preformed [FeIII3O]7+ benzoate triangle, LnIII salts and the ligands in different solvents under normal or solvothermal conditions lead to several mixed FeIII-LnIII species with different topologies. Furthermore, new species stabilized under solvothermal conditions can be obtained via a solvothermal treatment of the FeIII-LnIII compounds which result from reactions conducted under normal conditions. The resulting compounds were structurally analyzed by single-crystal X-ray crystallography and X-ray powder diffraction. The magnetic properties and spectroscopic studies were investigated using magnetic susceptibility measurements and Mössbauer spectroscopy. Magnetic studies reveal that three analogous hexanuclear {FeIII4DyIII2} compounds as well as a {FeIII7DyIII4} compound display single molecule magnet behavior. 162 pp. Englisch.…
