الوصف: International audience ; We report the synthesis, structural characterization and magnetic properties of a series of Co(III)/Dy(III)complexes built up from an N-alkyl derivatized amino-alcohol ligand diethanolamine, functionalized withC H alkyl chains (n = 3, 4, 6, 8 and 10). While n = 3 afforded a butterfly {CoIIIDyIII} core, the other alkyl n 2n+1 2 2chains (n = 4, 6, 8) afforded hexanuclear triangle-in-triangle {CoIIIDyIII} complexes as shown by single- 33crystal X-ray determinations. Infrared spectroscopy allows us to characterize the C10 derivative complex, which did not crystallize. Magnetic ac susceptibility data collected below 10 K at driving frequencies up to 10 kHz under zero-dc field and up to 1 T provide insight into the SMM behaviour of the studied com- plexes. The characteristic time of the magnetization dynamics can be understood in terms of the com- peting Raman, Direct and Orbach-like mechanisms. A relationship between the magnetization dynamics within the family of complexes and the increasing alkyl chain length is discussed.
